i just got a call to my cell

I picked up the call (on my cell)They tried to tell me that I had won 2500 Air Miles or something like that.  But, the call hung up shortly afterwards.

Got a single call from them, one ring. 519 is Ontario, but I never called there or gave any telemarketers my number as far as I know.

I just got a call from this number on my Telus cell and I did not answer, nor did they leave a voicemail.

this number called my cell twice. I call back, call disconnect after one ring.

my son just got a call from (519) 987-2525 on his cell, he wasn't close enough to catch it, these calls keep coming on my landline and today is the first time to hit my son cell phone,this is really annoying!
