MANY OF THESE CALL NUMBERS SEEM TO ORIGINATE FROM THE SAME SOURCE OR CALL CENTER.
When you get any kind of unsolicited calls (robo generated or not) and you get a live person from the caller, when they greet you or ask you a question you just respond "What do you lying cork soakers want to scam me out of today?" If they respond or not just keep repeating your opening phrase over and over and over whatever they say or try to respond with. Do this until THEY hang up. If we all respond like this to all unsolicited and illegal calls they will soon get the message. I do this with all unsolicited illegal calls whether if is from Microsoft about computer errors, the IRS or someone wanting to sell back braces or "Rachel" from credit card services. I am on the DO NOT CALL list so that makes them fair game Try it!

called again. Shows up as ATT but its not.

caller id says ATT but not ATT

It is a call center for AT&T and it is  100% legit.   They are trying to offer new services.    
If you do not want them to call you, answer your phone and tell them you are not interested and not to call back.

This lot phones us about once a day.

Eventually I'm going to do what I did with "Card Services" - answer the phone in German (I speak German).  I really ticked off the woman at the other end.  She said "You're going to have to do something about that d**n accent!" and hung up.

This number calls our house at least two times a day. If you answer the phone no one is ever on the other end - just silence. After reading about this online it appears that this is not AT&T (caller id says ATT) Recommendation is to file a complaint with the FCC online.

That is because this is not the real a T & T

Don't ever do the opt out on their menu. It just tells them you have alive working number with a live person at the end of it. If you get strange charges on your phone bill that is your own fault because you went through this process.

Never call a number that the scammers give you to call. That is part of the scam. Call the number on the back of your AT&T bill. If you have no business with AT&T just hang up or don't answer the call

It's not the real AT&T. Don't bother to answer the phone

And that's the things they are playing on you to see ATT and think AT&T like they could be trusted business. They are scammers do not answer the phone.

AT&T Will never ask you these types of personal information questions. It's a total scam hang up on them they're trying to get your personal information to drain your credit cards and bank accounts. And steal your identity.

Never never never go thru the take me off your list bs in the phone menu. This is not AT&T making the call it is a scammer. When you do that you just tell they they have a live number which they then sell to other scammers.

                                                         STOP CALLING THIS NUMBER  WE ARE ON DO ON DO NOT LIST

        WE ARE BLOCK THIS NUMBER????????        THANKS

Nasty oriental bi*** wondering if I have uverse high speed internet.... asked her "I don't know, do I? What is my account number?" Stupid idiot says I don't know that so I said #$%^&*(@)"?<@)(*&^%$#@! This is the second call from that w***e.

Caller Id reads ATT; not AT&T

This is obviously a scam. All calls I get that are genuine from AT&T are either in my area code or are 800 numbers. These calls were many months ago and were about my new service and then my request to change local calling plans.

These idiots call at least once sometimes twice a day.Caller ID says ATT.Like I want more AT &T services.Of course they never leave a message.

Caller id claims it is from ATT and to press five if you no longer want calls from them.  I did press 5 and we will see if I no longer get calls or start getting strange charges to my phone.

Too bad there is not some hit team that we could call to get rid of these jerks.

Isn't the first, nor will it be the last call from this number.  But is it me, or does anyone else find it strange that AT&T U-Verse Bundle Plans is being advertise for only $59 in the comment column?

Like others, I have received many calls more or less daily from 323-250-0528.  Another today. BUT this is the first time I was able to talk to someone long enough to establish with some confidence that this is in fact AT&T telemarketing. I did not accept any offers as a result of this call, but before she hung up she said I should call 800-288-2020 to verify this call is legitimate. I decided to find out what is going on and called the 2020 number.  It rings in to an automated system which is actually an AT&T number.  I fought the robot for 10 or 15 minutes until it gave up and connected me to a human.  I was able to establish that this is in fact telemarketing by AT&T to promote their U-VERSE service.  I asked to get my number removed from this marketing program.  This got me switched to the NUISANCE call center.  Another robot to fight with, and finally a recorded message which explained how to register with the do-not-call list.  Then GOODBYE, followed by a hang up.  So, I have concluded that this is NOT fraud, but it IS very aggressive telemarketing, which the do-not-call list should have eliminated.  Very discouraging, as I am stuck with AT&T for phone service so I can get the DSL internet connection.  I would like to dump AT&T.

This number has been calling daily, sometimes twice a day and as late as 11 at night, for weeks now. We hardly ever answer but when we did we asked to be put on the DNC list. After requesting this several times and still receiving regular calls from them I called the number myself and used the automated system to request to not be called anymore. It said it could take up to 30 business days which is bullsh*t, if you ask me. If they don't stop calling I will probably call the REAL AT&T and have the numbers blocked. It's such an annoyance.

This number calls our house at least once a day every day.  Caller ID shows ATT.  They never leave a message and we don't answer the phone.  If we need anything fro0m ATT we will call them so they might as well quit calling as we will not answer the phone and they are just wasting their time.

I've gotten calls from AT&T Svc Center before, but the area code was usually Texas or Illinois.  This time the ID said ATT, but the area code was local.

Called last night around 9pm.  I hung up on them.

I could pick up and ask them to hold, but I just don't want to be bothered even with that.  I've asked AT&T not to call me before, and it has been way longer than 30 days since I made that request.  I've asked Time Warner Cable not to call me, and they still do.

I hate all big companies like this.  And I get so many unwanted calls, when the phone rings, I'm thinking "Another unwanted call, I know."  If I got this many calls from employers, I would have had a stupid job long time ago.  These calls always come when I'm home, (breakfast, lunch, dinner, and after 8pm) so I can usually hang up on them.

If I want to talk to AT&T, I'll call THEM.  Llike some above posters, I don't pick up unknown or unwanted calls.  I hang up on robocalls too, though they are still tying up your line until the recording finishes.

Whether it's really AT&T or a scam, I don't want to talk to them either way.

I see from some posters the number isn't valid when calling.  My opinion is that legit companies or phone calls will display a working, valid phone number.  Numbers out of service or disconnected sounds fishy to me.  They don't want you to know where the call is really coming from.

It's true that "ATT" makes people think "AT&T".

Just got a call from this number. Caller ID says ATT. Caller said his name is Eric, has a heavy accent. He had the address, claimed he has my SS #, but that for security reasons, couldn't state it, then asked for my birthday, which I refused to give. I know, for a fact, that AT&T never asked for birthday or SS# when I got my phone, though he claimed that's how he knew them, but in Nov. and Dec. I had scheduled service to get U-Verse and WiFi installed, which didn't work out because they had disconnected my phone before they were to arrive, causing me to be unable to let them into my building.
He said that they, AT&T, wanted to upgrade my service to U-Verse, and that I'd need a new modem, to access U-Verse and WiFi and that it would be free. That was what really made me take notice, because AT&T was going to charge $190.00 for that upgrade, and the disconnection of my phone that morning, just two days after being discharged from a 4 month hospitalization, leaving me unable to let the nurses into the building, or contact my family, causing great panic, was the reason I cancelled that work.

 I did call the 323-250-0528 and all I got was an auto-mated service saying it was AT&T and to be put on their DNC list press 1 Which I did... I was told it would take up to 30 business days to be taken off their call list. Hope that works, but not holding my breath on that!
G_d I hate auto-mated phone calls.

 Here are a few other numbers that my caller id comes up with...
989-220-3853
210-255-3192
321-224-8390
and they all have "ATT" as the caller. I have called AT&T on the first number and asked what AT&T wanted because I couldn't get through to the first number. I actually called AT&T on the number they give you when they send there bill to you each month. The person I talked to at AT&T said the number that had called my phone "WAS NOT AT&T" that had called. I told her the name and number came up on my caller ID. She still said, it wasn't AT&T. And that I should file a complaint with the FCC.. I told her that is what I was actually doing as I was talking to her. Other than that there was nothing they could do about these calls.
 File a complaint with the FCC on every call you get from these SCUMS. If enough complaints then maybe they will do something about these spoofed calls trying to scam people.

We've also been getting calls from this number, about twice a day.  I tried calling but it said the number was not in service.  It's easy to say you can ignore them, but I still have to get up and go to a phone to find out who's calling, and then put up with ringing 4-5 times! I answer in the hope that I can start talking to them about religion or something and waste their time like they're wasting mine.

I just called this number (several missed calls have been recorded on my phone.)  It was an AT&T number.  It gave me the option of being added to their "Do Not Call List".  I followed the prompts and hopefully won't continue to receive the daily calls from them.  Yes, I am on the National "Do Not Call" list, but I think as a former customer (just cancelled service), they can probably legally still call me.
