I believe it is Ally Bank calling. They handle all the GMAC notes now. If they're calling you, you can believe you are late on a payment or something similar. You can't put them on Do Not Call List as they aren't a telemarketer; they are trying to collect funds owed them and have a legitimate reason for calling. You CAN stop them from calling by answering phone, ask what address to send a payment, use that address to send them a Cease and Desist letter (search for sample of C & D letter on Google). Send letter certified to get return signature for proof they received) and the phone calls should stop. Good luck.
