Overpaid on my account and wont pay me back

My account was in arrears on Edgars and then i paid my account in full but with a little more. When i went back to Edgars a month later to try purchase something they advised me that my account is closed even though my account is not in arrears anymore - actually there is some money on my account as i overpaid the last time. Since they closed my account without even notifying me i thought stuff them - then when i asked them for the money that was on my account when i overpaid they said i had to bring 3 months bank statements as the account was closed, but i did not close my account, they did. Even though i had my id with me they would not even assist.<br> Actually the manager on duty Molife Mokene would not even come out to see me or discuss the problem with me. The supervisor on duty Zanele Lewu just stood there and demanded i give 3 months bank statements before she even tries to pay me my money...i mean really, this is ridiculous and i cannot believe that Edgars policy is after they closed my account they still want the bank statements. I do not want my account re-opened as you closed it, i just want my dam money that is actually mine.
