On XXXX XXXX, 2015 my husband and I applied for a mortgage loan with XXXX to consolidate credit cards. In XXXX 2015, we contacted all our credit card companies asking that our accounts be closed and no more charges or interest charged to account. On XXXX XXXX, 2015 XXXX XXXX sent to Citibank a check for XXXX which was an overpayment to Citibank and when I talked with them they said i was due a refund of {$590.00} amd the check would be submitted to me in XXXX to XXXX business days. Today, they sent me a statement saying that I now owe XXXX. {$10.00}. for XXXX 2015 because i was charged {$600.00} in interest for XXXX. They charged interested even though the accoutn was closed in XXXX 2015. XXXX they told me i would be refunded XXXX for overpayment and now turn around and charge me {$600.00} after acount was closed. Do I have any recourse in getting the {$590.00} refunded to me? I have been a loyal customer of Citibank for over 40 years and am very disappointed XXXXwith XXXX action. What can you do to help?
