The FTC just took down 5 of these scum suckers. Obviously they have a few more to go.

I have greatly reduced the number of calls to my cell phones by going to my carriers website (Verizon) and they allow me to block up to 5 numbers for 90 days. Since these scum change numbers every 30 I have had a very peaceful time. Call me once shame on you, call me twice shame on me. I also put it in my contacts list under Scum Suckers and assign it NO ring tone so at least after the first call they won't bother me anymore (I have filled all of the numbers in each and am up to Scum Sucker 47 now). This is only a whack-a-mole solution however it is the only one I can offer.
If you want to stop these calls then you need to dry up their revenue source. Your phone company is charging you a fee for caller ID. Your phone company pays the scammer for sending their caller ID information. Your phone company pays only a fraction of a cent per call and you pay $5 to $15 to your phone company. The scammers send out millions of calls per day which amounts to a significant amount of money however your phone company is charging a large amount to millions of customers. This may have something to do with the phone companies inability to stop these calls. You can also see why the criminals keep calling even though they know you won't fall for their scam. If someone does make the mistake of answering the phone and falling for their con then it is just icing on the cake for them. These people are the lowest form of filth on this planet.
In order to stop this we need legislation making it illegal to charge for caller ID. If a phone service wishes to operate it would need to provide the caller ID at no charge to other phone providers and to it's customers as part of the service. Here is the $50,000 solution that the FCC is looking for and it doesn't cost anything.
Many of the disposable numbers come from Pacific Telecom Communications Group and they are currently under investigation and in the midst of various lawsuits. (The principles involved have been part of actions by the FCC under other business names). Here is an excellent blog site that I found that explains how this company is getting away with this activity.

I would like this company to remove my number from their list. They call about reduced interest rates and refinancing my credit. I have asked several times to be placed on their do not call list.

I got a hold of someone a this number by pressing 1, but they were extremely rude and called my a liar several times.  They were asking to lower interest rates on credit cards.  I told them to stop calling me!!

UNSOLICITED and UNWANTED call allegedly from my credit card company about lower rates...BUT it isn't...it is a scam !  I have an unpublished number on the do not call registry and I have tried to speak to them about removing my number but the company representative just hangs up on you.  Best advice, don't answer calls from people you don't know.

They have been calling me every afternoon also. Make it stop please.

I tried to press 1 to ask them to stop calling me. The woman hung up on me.

I've been getting calls from this number lately. The key with any of these numbers is DON'T PICK UP. Sometimes the same scan will stop calling if you stop answering, but they'll start to use other fake numbers to try and check to see if your number is active. Don't answer any calls if you don't recognize the number. Invest in voicemail so if you actually miss a call, the person can leave a message!

It's those credit card scammers. They prey on gullible people, especially older women who have had strokes. Why these criminals aren't shut down and in jail is beyond me. Maybe Bank of America and Citicorp secretly own them.

Spammer, but even when you press 1, they do not connect you to anyone.  It's like a scammer whose sole purpose is to annoy people, rather than collect money.  Bizarre.  If anyone knows how to permanently block "Anne"  from account services, please post!

Anne from Account Services -- lower interest rate

I get these calls all the time. Looks like they've changed to a (202) area code now. "Anne" from "Account Services".

Whoever owns this site, should add "phishing" or "scam" to the pull down menu at the bottom of this form.

Been getting calls about lower my interest rate my credit card.  If I stay on the line to speak with someone and ask them to take my number off the calling list, they just hang up.

This Number has been calling for weeks, when I pick up no one is ever there. Then when I call back my phone says I have reached a Non-working number, or I get the busy signal. This number calls me about every 2 weeks.

Damn I hope it wasn't the President. I made a campaign contribution last night!!

Same here...when I said "Hello" the caller hung up.

Just now... Called and hung up.

I got one about 5 minutes ago
