UNDISPUTABLE UNAPPROVED DEBIT ORDERS I took a loan from a certain company and they sent me a debit check and I approved it

UNDISPUTABLE UNAPPROVED DEBIT ORDERS I took a loan from a certain company and they sent me a debit check and I approved it. The money was successfully debited from my account, however two more debit orders went off on my account that I don't know about,isn't their system support to pick this up and then to check with me before my money was taken. And it's not the first time this is happening with Capitec. Now they telling me there's nothing they can do. With Capitec it literally feels like I'm putting my money under a mattress Not safe!!! As soon as the Ombudsman assists with this matter, I'm changing banks
