Credit card scam. Received many calls & did not answer. Got miffed. Answered and kept some dumb bimbo on phone for 15 mins. Assured her I was interested in reducing my credit card interest rate. Hard hard time not laughing when I kept explaining my credit card is an American Express Black. She had no idea what I was talking about.
I usually wait for them to get on the line and insult them before they can hang up, but I like the idea of screwing with them for a while. I stopped being nice to them, I have been hung up on way too many times.
If you list your info on a job search site or something like that check th eprivacy policy many of them sell our information and that's why you'll get calls even if on the Do Not Call list
