"you have been selected to win XXXX Airmiles press 1 to claim your prize"Sandos Resort was my Airmiles "deal" of choice.    Here are some of the key things they say when I said what company routes the calls to them.  "I don't know, I'm not the IT guy to know the system".  "I would be working for corporate if I knew this informaiton".  He didnt' want to give me the information.  I told them that this is a shady way of doing business if this is indeed legit.    FYI he said he was from Mexico (had a spanish accent for sure). "You are the one who picked #1 sir"... grrrrrrrr......Keep them on for a while just for fun.  It wastes their time.   Give them fake credit card info off the internet.  Lead them on for a while.I asked what companies are involved.   I got: Airmiles,  RCI Resort companies and Sandos.   I was told I can call Sandos Resort and still get their rep to get a deal with them.   I asked if they ask for my credit card over the phone and laughed....  People are stupid enough to give a card number over a cold call?!   DUMB.  This is why they do it... stupid people that get Scammed and then we get calls.  Or stupid people that actually buy this deal perpetuating more cold calls.

they left no massage.

no its not actually.  It is faked, and you would have to do an actual call trace to find out where it is coming from.  This same scam has been quasi-legally operating for a number of years, and the number constantly changes, but the "you've won xxx air-miles" message is always the same

On July 9 got a call from this number, I refused to answer as the number was strange to me and looked like a scam.

Missed a call to my cell, glad now that I did. I usually try to talk to them if I do pick up because that's the only way to get your number removed if they're operating "quasi-legally" as someone else suggested.
