Credit card scam. Opportunity to press 9 to be taken off call list but doing so someone answered and said I could lower my interest rate on my Discover card. I do not have a Discover card.
Its obviously a scam but I decided to spend 20 minutes talking on the phone with them and wasted their time asking about the algorithm they use for lowering their rates. I then called them back on the number and said that I was from Credit Card Services and would like them to give me their credit card info. that was kind of fun.
