Just a silent or hangup call.

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.

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.

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 don't answer calls from numbers I don't know, I am also on the "Do Not Call' list.

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.
