This is a scam don't accept

It was a call from WESTJET claiming I was a preferred customer (i fly 2x with kids so about 8-10 flights yr w.westjet) but i know they would not call me....so I hung up prior to pressing 1 to see what i WON....as i know i never entered a contest therefore would not win from something i never entered....

Just got this call on my cell - November 3, 2012 in southwestern BC. When I picked up, I just got an automated message saying "6UV1 The number you have called is not in service". Once I hung up, I got a missed call notification for this same number (not sure if that could just be a phone quirk though). The phone was in my hand at the time, so this whole thing is very confusing, especially the automated message when I answered.

Phones home and cell oct 25 2012.  No message.

They are still doing it, but now using 403 numbers instead.  3 calls in 1 day, until I hit 1 on the third call can started to lay into them, then they hung up on me.
