Edcon accounts nightmare

Tried to close my account. First they sent me the amount outstanding, which I then paid. When the slip printed, showing my payment, suddenly there was another R26 odd rand left to pay. I paid the R26 odd rand, went to the accounts department at the back of the store to close the account. The lady that assisted me there was friendly and helpful, but the one on the phone line said she can't close the account because I have to send them an email with the proof of payment. Waited over the weekend so that the cash I paid at the store can reflect on their system, only to be told on Monday there's another R1.80 outstanding. Went to go and pay that also in store cash. Waited another day for the amount to show on their system. Phoned to close my account, when I told the lady I want to close my account, she begrudgingly told me that she will set it on the system, but I have to wait another 30 days, which means they will probably take another monthly fee from my account. I also haven't received any email confirmation to acknowledge that my account will be closed.
