In XX/XX/XXXX, I had some unexpected expenses. My car payment for the month was due on XXXX/XXXX/2015. Due to an out of town family situation, I did n't call Ally until XXXX/XXXX/2015 to request a deferment on my account. Up to that point I 'd had a perfect payment record for at least a year so I was immediately approved for an extension, 1 month per my request. I verified my information with Ally. As I have a physical address and PO box , I requested that it be sent to the post office. As a condition of the extension I made an immediate payment of {$170.00}. The actual amount to be paid was {$170.00}, but due to the language barrier, I was n't clear on the specific amount. I was then supposed to wait for my paperwork in the mail. By XXXX/XXXX/15 I had not received it. I called and talked to many representatives who said it was mailed. I was concerned about completing the transaction prior to the 20 day period of the extension terms. After many conversations, a copy was faxed to me. I immediately signed it and faxed it back. I watched my account to see if the extension was reflected, again getting nervous about the deadline and any impact to my credit. Again, after several conversations, I was told it was recieved so under the wire, I made the final payment of {$230.00} ( {$230.00} was the intended payment ) which would have been for the XX/XX/XXXX payment. I would then go back to my regular payment of {$590.00} for XX/XX/XXXX. Upon checking my account for my XXXX payment, I found a past due amount of {$170.00} with a late fee of {$29.00}. Again, after many conversations Ally reps have aknowledged that since the original document was sent to a PO box , that it was not valid. The payment I made to start the process for the extension was not applied to the extension, but my XX/XX/XXXX balance. I have spoken to a myriad of representative in the U.S. and even a manager in collections who acknowledges that this is what happened. They argue with me that I owe this when the copy of my extension agreement indicates no other charges. The last manager I spoke to, a gentleman named XXXX, said he would look into the situation and get back to me. This over the peiod of 2 months is still unresolved.
