call came in at 12:55 p.m. and person (or machine) on other end hung up.

They keep calling and hanging up - no one there. Irritating.

Recieved a call and they said that they were Dalhousie University. Wrong area code. Definitely a scam operation.

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.

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