Just got a call from these bozos. Shows up as ONTARIO and the number (613) 216-2172.

Since we've been getting these daily I finally presses 6 to talk to someone. Apparently we qualify for a credit card rate reduction.

When I asked from which bank they were calling, they hung up.

This one doesn't pass the smell test.

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:

The call came in - Caller ID had the number and "Ontario".  I listened to the auto message and then pressed 4 to get the live operator.  Got a guy.  He started into his routing when i interupted and asked where they got my nimber.  He replayed that they do not have a list.  I started to then say take the number off the list - "What part of 'We do not have a list' do you not understand?" and then "If you don't want our calls then unplug the phone and shove it up your a**".

Caller ID says Unknown Name, I called back and it says message box full.  No idea who it is.

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.

didn't answer when i picked up.  afterwards,  i accidentally pressed to the number to call back.  turns out, they're some sort of loan modification co.
