Please refund my account.

I am sick and tired of calling AB. I spoke to African Bank in September to arrange for my debit order go off on the 27th of each month I called them on the 6th of October but the next day two debit orders went off on my account. Yesterday I called in again, asking them why that has not been putted in place. They promise to put my debit order for the 27th of November and I will be paying R500 as agreed yesterday. this morning I received an sms from the bank stating that R376 has been taking on my account.I need my money back, I don't have transport money. I can't wait to close this account and move away from African Bank.
