We have had them call numerous times. Blocked the numbers but they keep calling. No room left to block any more of their numbers unless we remove other numbers.

Same thing, called and didn't leave a message. I'm in Alberta. I just set my phone to block these numbers forever, works every time :)

Claims they are calling on behalf of ADT home security

They will  not leave a message or identify themselves. I refuse to answer such calls.

Must be starting their rounds in Canada again....Did not answer and they hung up before voice mail kicked in. Probably a telemarketer...

Only rang twice but I wasn't going to answer any how.
