Dealer processing center. They have been calling me incessantly for over 2 years now. They try and sell extended car warranties. They even send official looking snail mail mimicking the dealerships post card. I must have been called from 10 different states over the past 2 years. I even told them I don't own the car anymore. Avoid these jerkoffs at all cost! They are scammers trying to sell people extended vehicle warranties.
