i have no idea who this is

Received a phone call out of the blue saying: "Congratulations" because they were "awarding" me a $100 voucher for visiting one of their affiliate websites. They wanted my credit/debit card number to cover the "cost of shipping" the voucher (~$4). When I asked them to specify what "affiliate website" that I visited, he quickly glossed over any specifics. I said I do not give out my credit/debit card number to a stranger over the phone.  He then said something about not "forcing" me, etc. and I hung up. The phone number emanates from Colorado (Cherry Creek area of Denver) and supposedly belongs to "Echelon Telecom of Colorado"

Call, no msg. Thanks for info
