Closing account due to bad service on unauthorised debit orders

For 4 consecutive months now I have been to the bank to reverse debit orders on my account that was not authorised by myself to go through my bank account. I have instructed the bank on numerous occasions not to allow unauthorised debit orders on my account. Every time it costs me time and money to go to the bank and reverse these debit orders. This month, another 4 debit orders went through and will now again cost me reversal charges and time and petrol. I am at the point where I am going to close my account with Capitec and take my business elsewhere if I don't get refunded all the bank charges on these unauthorised debit orders for the past 4 months.
