We've experienced the very same thing for the past 5 days with regard to (416) 484-5165.  Calls have been received daily, with either no message being left or no one on the other line when there's someone home to receive the call.  Further, the phone number is for outgoing calls only.

They just keep calling.... i hang up on them now...

good to find out who this is. cant stand it when i don't know who it is and there is no msg

Called several times won't leave message. Few times am standing by the phone but refuse to answer.

Got 2 calls from this same number.  No answers.I did get a call from TD ins. trying to sell insurance.  Same number.
