I filed a complaint against Ally regarding my car loan earlier today however I finally was able to speak with an agent and learned why I have had so many issues during the four years. When Ally credits a payment they credit the payment to next or current car payment but do not credit any of the funds to any amount that may be " in arrears ''. When the next payment comes in they continue to credit the entire amount to the next payment regardless if there is a late fee or shortage in the previous/current month on the account. This keeps the customers account in a constant shortage which then incurs additional late charges and sets the customer up for reporting to the credit bureau. This is what has been happening to me since I became an Ally customer over 4 years ago. I have complained several times to Ally but they deny doing anything wrong. Today " XXXX '' told me how Ally credits payments which explains why/how Ally has been overcharging me for the last 4 years. Per " XXXX '' this form of accounting is perfectly acceptable. If this is the way a bank/credit union is suppose to credit payments then I have several other accounts to file complaints because none of my other lender do this underhanded accounting. I make more than XXXX payment per month so instead of Ally crediting my payments to current month or any arearage they are crediting payments to potentially future payments and leaving me with multiple late fees. When I make a payment I expect the money will be credited to what I owe - late fees, current monthly payment if additional to principle. I expect this every month.
