Hmmm, interesting, i just got a call from this # too.  Funny, got a similar call last week in 519 area code, had exact same complaints

called my cell today at 6:05pm left no message did not answer as number unknown

Told my husband that he had won 2,000 Air Miles, and, if interested, to press the #1.  He did that, and then there was silence.  I told him to hang up the phone.We have a 306 area code (in Saskatchewan), and the call was at 2:10pm CT.

no message, they hung up early in fact

Got this call just now on my cell phone...it claimed to be from "Airmiles Canada" and that I had won 2,600 airmiles.  I hung up (even though I really wanted the airmiles).

I recieed 4 calls in  a row from ths number on my cell phone, it would not even finish ring once then stop and it would ring again as I said it did this 4 times in a row and said I had  4 missed calls on my phone
