Unauthorized debit orders

I recently opened an account with capitec, and suddenly I have a debit order from clientele, I've never had any policy or communication with clientele and I fail to understand who authorized them to debit my account, R238 on the 27th of February 2021, and the bank says I must speak to clientele to reverse the money, why when I never spoke to them before, you allowed them to debit without my permission so reverse my money.
