Who can I call that would be willing to re-finance my very high interest auto loan, with my bad credit?

Question by sis2sis: Who can I call that would be willing to re-finance my very high interest auto loan, with my bad credit?
I recently bought a car, and had to take a loan with an interest rate of 24.99%. That means that I'm going to pay double for my car once its payed off. I've been hearing that I can try refinancing after 6 months of "on time" payments, but I've applied twice now, and been turned down both times. Does anyone know anything about this. Who I can call? Or how long I should
