JPMorgan Chase Bank Account Or Service Complaint

JPMorgan Chase Bank account or service department,

Other bank product/service Account opening, closing, or management California

On -/-/15 I went into my Chase branch to pay off my credit card balance in full. I overpaid by $330.00 so that any additional interest - $110.00 would be paid from that and then refunded the balance on the next cycle. After the cycle completed, I requested the difference to be transferred to my checking account. Because I asked for a transfer to my checking account and not a check, they had to put the $23000.00 back into my account as a charge and then credit the payment incurring $160.00 in interest. and still refunding me, now making the account have a minimum payment due of $44.00. When I closed the account they took it off my account dashboard, so I did not know I owed $44.00, thus missing the payment '' 2 months after the account was closed and the statement showed that they owed me money and not the other way around. I have gone into the branch and talked on the phone but they say there is nothing they can do.
