Unathorised debit orders from my account

I found out from my bank statement that the company deducting R49 from my Capitec Account. I did not athorised any deductions and this was under false illusions. The reason for finding out late was that the amount of R49 was small and i did not get an sms for deductions under R100 from my account. I want my money back for all the deductions taken from my account.
