unpaid fees standard bank ****s.

I am leaving standard bank ,Iv been banking with them since 2013 up until now .I went to them looking for help regarding debit orders ,there are unknown companie who are debiting my money and they couldnt assist me to stop them.I decided to transfer my money to another bank every time I got paid.Those companies continue to debit and standard bank charge me unpaid fees which R130,per debit order.Theres a company that debited 3 times in a single day and the bank charged unpaid fees 3 times in a single day hows that possible?? I am moving my salary to capitec now ,I cant be paying almost R1000 every month for unpaid debit order fees to standard bank ,this is not fair at all
