They won't close your account.

I called about an issue to which I mentioned to the consultant that I intend to close my account. She gave me the number to call to call when I am ready to close. I went ahead and paid the outstanding of my credit and called the number to have my account closed. Now I am being told that I did not follow procedure to have my account closed and I should have not paid and I am still required to pay a fee. I do not understand why is it that I have to be charged for closing fees etc when my credit is on 0. I am not owing anymore and closing because of high fees and delays in resolving matters. It shouldn't have to result in me having to be below the credit limit before I can close. yYou are taking me from covering my debt to creating debt before my account is closed. That's crazy. The consultant tells me I should have done my due diligence before paying off my account, as if fsps make signers aware of hidden discrepancies. I can't wait to have my account closed.
