unauthorised debit order

or as long as i have had loans with african bank i never realised i was being debited an amount of R69 for long period of time until i was told by my bank about it called STOK VH , R-69.00. i would really love all my money back from all the times this was debited dating as far back as 2016 using my id number and different 6 digit reference number same as my debit orders for their loans every month. this was unauthorised by me. SA payment exchange is ***gy backing off my debit orders of african bank and debiting the stated amounts every single month.
