Received several calls from Ontario, CA (613) 216-2172 with no message.  Called back and no company name was given, so I hung up.  Now I'm charged for two international calls to Ontario, Canada, which totaled over $6 with all the taxes and carrier cost recovery fee.

It's a scam.

Don't know who this is but tired of them calling and leaving no messages

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

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.

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."

If they are indeed based in Canada -- filing a complaint with the FCC or FTC won't matter, will it??  The U.S. agencies would have absolutely no jurisdiction.

I am very annoyed with these calls, as well.
