I am also on the DNC list, but every time I try to get some info to get them stopped, they hang up.

This time, I played along.  The automated message said they were from "Credit Card Services".  When I spoke to a representative, he asked if I wanted to lower my credit card rate.  I told him I did.  He asked if I had over $4000 in credit card debt, I told him I did. (even though I have no credit card debt.)  I was trying to get to the point where he would ask me personal information so I could question him back.  

But then the curious question happened:  "Are you over 70 years old?"
I replied no, thinking a credit card company would be interested in younger people.  With that, he hung up.  

It concerns me that they are targeting older people exclusively.  My grandparents would probably fall for this-

File a complaint with the FCC Online here:  http://esupport.fcc.gov/complaints.htm  These people should be shut down because they use automated machines and do not allow you to tell them to stop.  Their mailbox is "full."

Received a call while driving and there was no one on the other end.  The Caller ID indicates that the origination is in Canada.  I do know that a lot of fraud is now coming out of Canada, targeting people here in the US.  The most often used is by mail and includes a large check that is drawn under a legitimate company name and a phone number in Canada to call to inquire how to get the money... which involves sending money to them for "taxes" on the "winnings"...Though I have tried to "Call Block" this number through ATT, the service will not allow me to do so!

Just received a call this morning from this number. ?I do NOT answer any calls where the ID is "Blocked", "Unknown", "Unavailable", Anonymous" or "Out Of Area" or I don't recognize the caller ID.  The caller ID on this call was "OTTAWA   ON", no name and then the number.  Since we know people in Ottawa, I called the number back twice and both times I received the, "This Number Is Not In Service". "Please Check The Number and Dial Again"!  From what has been reported here, I see that it s a scam.

Call came @ 2:11 PM EDT on 08.14.2009 -- caller ID read OTTAWAHULL, ON, apparently originating in Canada. If I don't recognize the name or number on the caller ID whomever is calling is wasting their time because I don't answer.  I've been on the do not call list since day one but that list means absolutely nothing because it hasn't stopped the calls.

I picked this call up by accident, as I was expecting someone to call.  When I just heard dead silence on the other line, I checked my caller ID and realized it was a dumb telemarketer.
