This number phoned me last night at 4:20 in the morning. A man left a message claiming to be from the National Control Centre for the post office. He even noted what time it was for me locally (in Nova Scotia). I deleted the message because I don't believe any government employee is calling people after two in the morning their time. I think this is bull, but I'm not sure.A similar number phoned me earlier in the day yesterday as well: (613) 734-8775Is this a scam?
