I listed an item on eBay, and it "sold" in 5 mins, to a new member (that day), who claimed to be someone named Janet Williams.  She/they created a fake PayPal email that said the funds had been deposited into my PayPal account.  But, the amount that was supposed to have been paid was way more than I invoiced AND they suddenly wanted me to ship the item to Nigeria to a Peter Williams.  The extra money was supposed to pay for USPS Express International shipping.  EBay & PayPal confirmed that it was a "phishing" scam, and said not to ship the item, (until the funds showed up in my account, which they never did!)
Report this caller to the police or whoever will listen!!!!  HUGE SCAMMER!!!!!

You need to google FTC sites and read about those prosecuted because of the dnc.  Quite a few there.  
They do in fact prosecute but first they have to have  to document enough complaints to establish patterns,  pursue,  and then prosecute when enough evidence to convict has been aquired.
In 2012,  the woman who headed up one of the "megan"  credit card services sites was prosecuted.  She got 17.5 years in prison,   her husband got  10 years for abeting,  and several workers got 2 years each.   The past couple months (as reported on this board) has had one of the "Rachel"  credit card scammers busted in Florida,  also
International cooperation arrested some of the scammers in India.    Not perfect but it does help.

You need to go to the DNC site and read/learn something about what it's for and how it works.

Because the DNc  is just a list.  It doesn't block anyones unwanted callers..   Just a list...
I would recommend getting a call blocker for that purpose.

These scums don't give a rip about any laws or DNC list. Besides the Fed Trade Comm (DNC People) don't investigate or prosecute any one. They simply gather reports.

My phone service lets me selectively forward calls from designated numbers - so These jerks are being forwarded to the FTC switchboard. Let them take the calls.
Some I forward to the State AG office, my congressman's office, or my senator's office. Unfortunately I can only forward 12 numbers. So I rotate them. Congress & senate don't do anything anyway so let them earn their keep by dealing with robo calls and scum bags

Recorded message about discounts for seniors.  I hung up at that point.  The caller id is hijacked.  I used to work for CDI, and they DO NOT make calls like this.  They are a legit software house.

I called the number back 2 times and it has push this prompt if you wish to stop receiving these calls and I did. Well it called back again and I wanted for the message to be over and told the guy on the phone to stop calling this number or I'd contact the Attorney Generals office and report them. He laughed. I contacted and reported them for calling a Do Not Call Number.

My caller ID says CDI INFO SVC

this call is constant, a senior alert.  it is a robocall

Repeated calls.  Seems to be no way to get off the list.

I've been getting calls from this number on my cell phone for a couple of weeks now, and they never leave a message, so I assumed it was a sales call. I just tried calling it back from a land line for the first time a few minutes ago, and got a quick busy signal.  Was hoping I'd be able to answer the phone when they call one of these times so I can confront whoever it is about calling me, but other comments indicate that the caller hangs up when the call is picked up. Will post if something different happens for me.

They keep calling and calliing....Don't they ever give up?  Still not as bad as those 876 Jamaica calls.  I get between 10-15 annoying calls per day!  Just goes into the ansering.  Seems like they would quit!

This company has called my home number at least 20 times in the last month.  At all hours of the day.  I wish I could get them to stop.

Calls several times a day. No option given to stop the calls

i agree with the others they hang up and dont leave voice mails...its becoming a major head ache.I wish they would stop calling.

SOMEONE AT THIS NUMBER CALLS ME BUT IF I PICK UP NO ONE IS THERE AND IF I CALL THE NUMBER BACK NO ONE ANSWERS IT.

Left no message

The caller has been harrassing a senior citizen, by calling late at night and just breathing.  Can the police do something?

What an irritating thing to be called almost daily, why can't someone do something about it.

called and hung up

Medical alert system for seniors they said it was free. So I listen to their sales pitch and found out that there is a $34.95 a monthly fee for the medical alert personnel. Just another scam.

Have received at least 4 calls from this number since mid February - I don't answer calls I don;t know - getting tired of them using up my answering machine and not leaving messages - I am on the do no call list but I don't think it is accomplishing what it was supposed to do!!!!!!!!!

Received calls as well from this number, same thing happened as to other,
no one on the other end, when I called back, rapid busy signal.

Robo call about some medical alert for seniors. I pushed #1 and asked the woman to remove our number from their database. She was fine and said she would do as I asked. Guess only time will tell.

Hi . How do you get on the do not call list. I got a call from this number today also...

i answered they hung up i did try to call them back from to different phones busy each time i have idea who or what they are but its very rude needless to say dont waste your time calling them

Keep getting calls from this number and I'm on the "Do Not Call List"!  So much for registering with the DNCLRegistry.  I don't answer calls I don't recognize....PERIOD!!

Received a call.. nobody there, no message. Called it, but only rings busy. I'm on the DNC list as well (for what it is worth). Filed a complaint with FTC. Caller ID shows as "Royal Oak MI".

Robo Call .  Hamgs up when answered.  It busy when calling back

no message
