Review Debit orders on my account

I would like you to stop debiting my account, you people came as people that supply loans but next thing I know R235.00 is being debited off my account every month. I don't need these services you are debiting me for. You are crooks in disguise, worst part I reverse your debit orders but every month you change the reference number. STOP YOUR NONSENSE!!! AND RETURN ALL THE MONEY YOU TOOK!!!!!
