During the month of XXXX 2015, I made multiple payments XXXX using electronic bill pay XXXX on my existing mortgage with Wells Fargo Bank in the amount of {$880.00} and {$1700.00} for a total of {$2600.00}. The total monthly amount due for the XXXX mortgage was {$1600.00}. Once I noticed the over payment, I called Wells Fargo on XXXX XXXX and spoke with a supervisor ( XXXX XXXX ) to inform him that I overpaid on my account and that I wanted the credit in the amount of {$950.00} returned to me. I gave XXXX XXXX my XXXX XXXX XXXX account number and routing number. He assured me that he was going to open a work order to have the funds returned to my account. I waited 5 business days and called Wells Fargo on XXXX XXXX and spoke with another supervisor in customer service ( XXXX ), and she informed me that Wells Fargo could not return the {$950.00} ( that they fully admit is a credit ) to me because their accounting system would only allow them to return the full amount ( {$1700.00} ) that was paid on XXXX XXXX. Upon hearing the explanation from the supervisor, I told her that I was not a person of enormous means and that I would accept a paper refund check in the mail from Wells Fargo instead of an electronic deposit to my account. XXXX told me that Wells Fargo would not send a paper refund check due to their accounting system. I ended the conversation by informing the supervisor that I would file a complaint with CFPB.
