CarMax, Inc. Consumer Loan Complaint

CarMax, Inc. Consumer Loan department,

Vehicle loan Taking out the loan or lease California

We have been making $1000.00 payment since - ( payment 24 ) to pay off the vehicle early ; I have called numerous times complaining about the payment history not reflecting the payment ; instead they are moving the payment due date into the future ; it appears they are charging double finance charges ; payment is $ -/monthly which includes interest however, you will see separate charges for additional interest and the interest charges seems to be excessive. I ca n't even understand the payment history.
