I make a court ordered payment monthly of $20. I do it online every time. 2 days ago I made my payment for this month and I have to enter manually how much I'm paying, so I entered $20, like usual. My problem I need help with is after looking later that evening at my online receipt, it shows that I made a payment of $463.00, which is the pay off balance. I make payment because I CANNOT afford to pay it off. I don't know what happened, but I entered only $20.00. The payment is due to post tonight at midnight. Is there anything I can do before tonight when it will post to have my payment reversed back to me. I will then make the right payment (once again). Any advice on what to do?
Thank you

There is nothing you can do at this point - the creditor (now that he's paid in full) is most likely not going to send any money back to you and continue the payment arrangement.
