Just got a call and when picked up the phone, no answer

Just got a call from this # on my cell phone. They tell you to press 1 to collect air miles with WestJet. I work for WestJet so I know this a an absolute scam. I pressed 1 to see what they ask for. Someone comes on the phone and asks if you are over 18yrs and if you have a major credit card. I said yes. They put you on hold and someone else comes on. He started talking about what I was going to win but then must have overheard the WestJet Boarding announcement in the background...he hung up.

I got a missed call today 13Feb2013 from this number. No message left, and living in BC I don't have any business in Alberta.

Got a call from this number on my Bell cell. Says i've won 2600 air miles, press 1 to accept...of course...I hung up.

Just got a call.  phone rang and before I could even look at you was calling me the call was ending. Weird... why call someone and hang up after 1 ring...

The same annoying "You've won xxxx airmiles. Press 1...". They always call line 3 here at work in the evenings. So this time I pressed 1 and got this guy who asked me if I am 25 or over and had a credit card. I said yes to both. Then I went on hold for a second and a second guy came on, so I shared some of my innermost feelings with this fella then slammed the phone down in his ear. They probably laugh at this, but it made me feel better.From now on I am going to tie up their people for 5 to 15 minutes. They only call once every week or so. SO that's 5 minutes out of my week. The more people that do this the better.Pretending you're really old and hard of hearing or just retarded makes the call much more fun.
