Urgent assistance needed!

Having been a loyal standard bank customer for all these years not only having a homeloan account but as well as my business and personal accounts i actually feeling like switching and moving to another bank.I have a constant debit order that is going off in my business account at least twice everymonth of a contract that has long been expired and cancelled but this company just keeps taking money out of my business account and i have to keep reversing the debit order everytime.I feel that if my business account cannot be protected and if standardbank cannot take this off i will have no choice but to run my account empty and switch my business and other accounts to another service provider.I am hoping that this matter can be resolved and that this does not have to be the option that i would have to choose.

Kind Regards
