Closing an account _A|_disaster_A|A. Please HELP!

I have closed my business account at Nedbank about 2 months ago. What a disaster! The wrong account was closed, my personal Internet profile were close, though I had 2 different accounts with them. Suddenly the debit order that was lodged on my business account, that was closed, went off on my personal account, after a call to the client services it was sorted out, and written back on my account. So I wanted to close my personal account, and went in to the branch at Lephalale Mall. The lady said that I had to phone the client services in the branch, so I did, and the lady said that I have to pay in R 133-22 to close the account. She gave me a ref nr. ***4 and said I have to tell the teller after I pay in the amount to close the account. And I did so, and told him and ask if he is sure after paying the amount my account will be closed. He confirmed. I receive a sms that I'm overdrawn again, the account is not closed. Phoned the client services Russel said the account has never been closed at the branch. Then the debit order we have stopped on my business account went off again on my personal account. The branch say sorry I never told the teller to close it. What now?
