received calls march 27, march 28 twice, march 29, march 30 ; person on the phone(always a male) saying that he called from "fresh air duct cleaning", laughing and hangging on you when you told them to stop calling...and he calls back next day!!

Received a call from this number in Windsor on 1 Apr 14, I did not answer and they did not leave a message.  I suspect telemarketers using local numbers...
