American Credit Acceptance, LLC Consumer Loan Complaint

American Credit Acceptance, LLC Consumer loan department,

Vehicle loan Managing the loan or lease California

I have a car loan that I have paid over $ 8k but they are reporting only $300.00 paid down on principal. I disputed the balance with the bureaus but nothing. I wonder how the bureau validated information when the company has not provided me with copies of my payment history as request amortization schedule. I need to know where my money has gone. No one is providing me answers or getting me records.
