Nuvell Financial Services - Won't stop calling.
877-688-3550 Ext. # 87542 Robert
Nuvell was bought out by Ally Bank - so if you had a car loan with either GMAC Finance or Nuvell - you are stuck with Ally. Even when you tell them you have made a payment online and give them the confirmation number, they continue to call - NUMBER WITHHELD on my cell. They just need to get the balls to answer the calls and actually listen to the customer. Even when I have picked up the call - they love to hang up on you.
Never get financing through a dealership again.
