I receive a call every day from this number. The guy is rude and was upset when I said I don't want to redeem a vacation. He said I reserved and paid for a vacation years ago and I am wasting it. He wanted me to give him more money for this vacation that I do not remember ever purchasing. I told him if I paid for it and did not use it then I will waste it if I want to and he hung up on me.

Don't beat around the bush with this chap, either hang up on him or let the phone ring with no kind of an answer. He'll continue calling trying to con you into giving out personal and financial info with a phony vacation offer if he's getting something. He's got to offer somebody else if you let the phone ring. Note the rudeness--possibly a good indication this bloke doesn't get much interest in what he's selling. Get on his nerves more by ignoring unknown numbers and making him lose interest in your number.
