I ANSWERED nobody there,  called back the number busy signial

I have been getting these calls for about 7 months... they did send me a "bording pass" and asked that I call them back with my Visa number card starting with a 4. I had told them the second time around that I wasn't interested, but the calls just kept calling. 5-6 times a week told them to stop calling me but they just wouldnt listen I finally told them if they call me again I was reporting them to the canadian authorities they stopped until today, I guess my number was added back into the rotation. All they are looking for is your credit card number DO NOT GIVE IT TO THEM! These are the 2 numbers they called me from this week (780) 628-0115 and (613) 686-3609 (this is a canadian number from Ottawa)

(780) 628-0115 - when I answer, nothing for a couple seconds then they hang up...

Keep calling saying I was selected for a 7 day pass to Universal in Florida plus other stuff.  All I have to pay is a depsot?  Legit or not??
