Rec'd (many) phone calls which I tried to block several times from this cell number.  The caller originated from T.O.  I finally answered because his repeated attempts came after 11 pm and constantly kept waking me up.  He claimed that he rec'd a text from my number saying something about facebook or twitter.  (He couldn't be any more specific.)That's BS, because I'm not into any social media whatsoever.  There's no way I could have sent him a text message.  Until now, I didn't even know area code 647 existed, let alone is located at or around Toronto.  I suspect this guy is fishing for new cell numbers.
