I keep receiving this call. I called it back and it says the number is disconnected.
Ottawa  ON  (613) 216-2172 appears on my caller ID

Receive calls from a toll free number and then when called back to check we are charged an international call fee.  We are on the DO NOT CALL list but apparently it doesn't matter to this company.  I usually do not answer unsolicited toll free numbers, but when we receive numerous calls from a particular number I sometimes check to see who they are .  Do not do this as we have been charged international fees on our phone bill.

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-

Have no idea who this is.  They leave no messages.  Calls at different times of the day.  Would like for them to stop.  We do not answer, but the phone ringing with unwanted calls is annoying.

This number has called several times for several days. ?Caller ID says "unknown name" then the #. As soon as answering machine kicks in they hang up. I'm on the do not call list, also.  Maybe next time I'll answer & let them know what they can w/obama mortgage plan.

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.
