I get calls from this number.  No one talks but there is background noise.  How can I stop them?

Caller (man) said I had won a prize package and I should go to Woodbridge to pick it up. The prize was from a ballot filled out in June 2007, did I remember filling it out for RCA, it's a big company, I must have heard of it. I asked why I would go to Woodbridge just because some guy phones - he claims to be Robert Fiddleton (sp?!), President of the company, phoning long distance from Buffalo (duh - my call display said (416) 360-4084) and there was obvious noise of a call centre in the background. I don't own anything made my RCA, duh...hung up on him.

I get about 3 to 4 calls every day from (416) 360-4084 and most of the time no response from the other side. Only once there was somebody on the other side identifying himself from ROGERS. Why Rogers should use this shady numbers? It is beyond my comprehension.

A fellow named Vic called from this number and claimed to have left a message yesterday, to which I called him out on it since I do not own an answering machine nor could my fish have taken a phone message since I haven't taught him that trick yet.

Yet another call today shortly after 1pm

receiving calls continiously every 4 - 5min since Monday! No one says anything and when we call back, it says that the number is out of service.
