On XX/XX/XXXX ( approximate ) I called Ally to request a change of date for my car payment. This was granted, they requested I pay an initial {$38.00} asap. ( letter dated XX/XX/XXXX ) Pmt posted before XX/XX/XXXX. Second letter instructed : Account Details Upon Finalizing the Extension-Including the scheduled payment originally due XX/XX/XXXX and all scheduled payments originally due on a monthly basis thereafter, all remaining scheduledpayments have been extended by '10 days. As a result, a scheduled payment of {$380.00} will be due XX/XX/XXXX and the remaining scheduled payments of {$380.00} each will be due on a monthly basis beginning XX/XX/XXXX. XXXX scheduled payments will be extended. The amount extended is equal to $ XXXXXXXXTo finalize vour extension. vou must pay the MINIMUM AMOUNT REQUIRED TO FINALIZE YOUR EXTENSION. As stated above this was completed. I have XXXX letters with these instructions, which I followed precisely.
