They called me the other day.  I kept them on the line for about 15 minutes..right down to him
getting ready to take my credit card number when I laughed at him, called him a scammer.. and told him I was deliberately wasting HIS time!  LOL  He got mad.

got a call july 7, 2011 7:30 pm saying I had won 100000 airmiles press 1 to accept....put me on hold and I hung up after about 30 seconds

Called my cell. Cell is pay-as-you-go phone from Virgin, so the idea that it's targeting Bell customers only is untrue. Phone number isn't listed anywhere. Refused to answer since it's my cell.

Recieved call mulitple times on work landline.  Prize 100,000 airmiles - press # to claim.  Have never responded.

DEFINITELY A BIG SCAM,BECAUSE IF YOU HAVE BEEN CHOSEN OR HAVE WON FREE AIR MILES,THEN THE AIR MILES COMPANY WILL AUTOMATICALLY CREDIT IT TO YOUR AIR MILES BALANCE ACCOUNT IF YOU OWN ONE..., BECAUSE THAT'S WHAT THEY DO WHEN YOU HAVE (WON) OR EARNED EXTRA AIR MILES,AS I KNOW THIS FROM EXPERIENCE......IF YOU DON'T HAVE AN ACCOUNT WITH AIR MILES,THEN WHY WOULD ANY PERSON PHONE TO TELL YOU THAT YOU HAVE WON AIR MILES?????????  
GOT TO LAUGH WHEN THEY PHONED US ON APRIL 30,2012 FROM THIS BOGUS NUMBER ALSO --->1-(250) 665-8989 TO TELL US THAT WE HAVE WON  A LOT OF AIR MILES.  L.O.L.
I WISH ALL THOSE VULTURES WOULD GET A REAL JOB.

It can cost on your cell phone, depending on your contract. Mine does
