I have a loan balance discrepency withAmeristar. I have overpaid the company on my car loan. They telling me that I owe them an additional $5000 plus on my 2001 honda accord sedan. They refuse to refund me my overpayment balance of $690 and are harrassing me everyday at home, on my cellphone and on my workplace. When I ask for proof of this outstanding balance they have none. They are blaming it on the previous loanholder (Motorists Acceptence). My contract plainly states any chnge to the contract must be in writing and signed by both parties, no oral changes are binding. I have addressed Ameristar with a request in writing for my overpayment balance and the title to my car. I have gotten nothing but a letter in return stating I owe them even more money now.
