Unauthorised Debits

hi have a problem every month with my ABSA account, I called the bank last month, this is so frustrating, because unauthorised debits are deducted and I have to go and reverse and have to pay for that fee and rates, I called them last month due to that my credit card debit did not go off and it effected my credit score rate seriously. I called and ask can I get a new account to avoid this they said no due to my overdraft ask can they transfer the overdraft to the new account they said no, how can you own bank not help you in this matter. this is my bank for years banking with them since I started working. my debits that need to go off doesn't due to all this debits that goes off before my own debits and effects my account. I already receive sms from unauthorised debit trying to debit my account already. I am going to change my salary to go into another bank, because I am tired of this every month on the 25th I have to go to the bank and miss work time for this issue.
