It's a scam.  Shows (613) 216-2172 "Ontario" on caller ID.  They are tryomng to get your credit card information.  File an online complaint with the FTC here:http://esupport.fcc.gov/complaints.htm

My parents have received numerous calls from this number and no on eis on the other end.  I call the number back (# on caller id) and it rings busy.  I added my parents number on the "do not call" directory but I believe these people are working from an old list.  Its very irritating.  I am sure the telephone company should be able to do something about this issue.

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.

Have received many calls from this number over time. Same comment as other. No one on other end. Probably a computer calling to nail down the most likely time you will be home. Common ploy. I have asked my number to be removed (Very quickly) and have just left the phone off the hook. Today I tried a dial back using my caller ID and got a jumbled bunch of static and not a return number dailing. These people are slimmy. Please help this number get disconnect. If you get calls from other solicitors, ask them where they got you number. Threaten to turn them over to the Federal Trade Commission. That might get their attention

I got a call from (613) 216-2172 and is was a recording with Congressman Steve Austria having a town meeting with his constituents...I put it on the speaker phone and listened to this garbage......He went on and on and on and on and finally I just hung up.  Too bad  a congressman has to call the US from a Canadian number......

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
