It's a Skype call, could be anybody

I got a missed call from this number and when I tried calling back it said the number was not in service.

got a call from BRG Business Associates Group just now from a different phone number though (416) 642-0882.  Address is the same, 216 Chrislea Road.i put up with half an hour worth of the guy talking, tell me i won 1 of 5 prizes.  booked a time with me and wanted me to go this saturday.he knew my name, my fiance's name and both our cellphone numbers.  the guy mentioned something about a purchase I made at Sears on 02/18/09 that qualified me for this prize.but i don't remember buying anything from Sears.

Got a call about it from some holiday place or something.
Person spoke really broken english (Indian accent) and said I filled out a form to win a prize in zellers or walmart or somewhere - except i dont shop there nor do i fill out forms like that.  said he has my address, which is right, except he said i live in north york, which is what the postal office says, i always say toronto.
told him i didnt fill anything out since he called and ask for Mr. or Mrs... and there is no Mrs. so couldnt have been me. Asked not to be called again and if I do it goes to the CRTC as i am registered with teh do not call list. He abruptly stopped talking and i hung up.

just looked on some other sites and this seems to be an issue with alot of people, however the rcmp and the opp have apparantly set up a joint task force to deal with this after several complaints about the same thing, which they call phonebusters 1-+1 888-495-8501

My sister is overseas to visit my parents for a couple of weeks and , every time she calls, this number appears on my call display. When I asked her she had no idea but said that she was using a calling card.
