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-

Got a call from them about 12:30PM today. Did not pick up and they left no voice mail. I went to the FCC site and filed a complaint: http://esupport.fcc.gov/complaints.htm

Have received numerous calls from this number.  Last week my wife told them
to stop calling us as we were not interested.  We then received two phone
calls at 4:20 and 4:20 a.m. on Saturday, March 21st with them replaying my
wife telling them not to call us.  This number needs to be investigated and
shut down by the Canadian Government.

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!

I get calls from this number 3 different times a day, every day. I finally decided to answer and it was a 60 second recorded messages stating that interest rates on my credit cards are set to increase tomorrow and if I want to lock in a low interest rate, I need to speak to customer service. So I did, I pressed 6 to find out who it was that was calling and to get more general info as to what type of scam they are trying to run. After pressing 6, it connected me to a live "Card Services" agent who asked which cards I would like to lock in low interest rates and the card numbers. My first and only question was "which bank are you calling from?" The guy paused for about 7-10 seconds (I could still hear his breathing and other background noise), and then hung up on me.Short of having the FBI trace calls connecting to my number, I doubt reporting a complaint with the FTC will do anything since most likely, the (613) 216-2172 number is faked using some sort of Spoofing (see spoofcard.com). The best thing I can think of to do is have everyone ANSWER the call and have everyone connect to the Card Services Agent and then hang up. If no one answers and connects to the service rep, he/she wont be bothered. BUT if EVERYONE connected the call WE would then be the ones WASTING these a-holes time, effort and money. The goal is to increase their operating overhead while wasting their time, frustrating them out of business. What would you do if the thousands of potential customers you were seeking suddenly all returned your call, flooding your system with junk leads and phone hang-ups? Think about it -- it makes total sense.
