I paid card in full based on a bill amount. The following month a Remaining balance of $7.32 was shown on a statement. I sent in that payment. The next month I recieved a statement showing a balance of $34.00. When I called, they said they had a pplied a payment using a previous account I had given them. I had notified them months earlier that the account was no longer active. By charging to this account, Citibank made an unauthorized transaction in which they say leads to a ballance on the card left unpaid. I complained in the store and finally reached an accounts manager that stated that the balance will be corrected as paid in full. I recently got another statement that gives a balance of $34.00. The associates told me the same thing that the reversed payment was not applied back to my account untill after my statements were sent. I spoke with another manager and stated that the payment withdrawl was unautherized and should not have even been attempted...He abbruptly ended the phone call and disconnected the conversation.
