I had a telemarketeer call me up one time trying to see if I was interested in their free vacation, all they needed was my credit card number to verify who I was. I told them I wasn't interested. They still wanted my credit card number to verify that I was who I said I was. I told them that I didn't need to give them my credit card number to them for me to verify who I am, I know who I am. At that point they said thanks for my time and hung up.
I'm just curious how many people give out their credit card number to verify their own Identities, for them to even ask that question.:disgust:
