We have received numerous unsolicited automated calls from Credit Card Services on our home telephone number despite the fact that our number is registered on the National Do Not Call Registry. On two occasions I have answered the calls and gone through the menu options until I'm speaking to a live operator.
During each phone conversation I have requested that Credit Card Services take our phone number off of their calling list, at which point they immediately hang up on me.
I do believe that Credit Card Services is a scam. They certainly are jerks on the phone. See:
