Unauthorized debit order - BESTINTERN

Good Day , I trusted Capitec Bank with my money. There is a debit order that went off my account by the name of 'Bestintern' (BI**********603) on the last two months 2021. I kept reversing the finds, but they kept deducting. I really know who the hell is this company. The debit order can't be reversed via app and I phone Capitec and they told me to reverse it, I did that exactly, but they kept coming back. I really don't know the company that debited my account and the number that they furnished as a contact it doesn't work. I asked at the bank to stop the debit order they said they can't and thus on the app is refusing. The bank cannot help to reverse a debit order and to stop future debit order. I am not safe with Capitec thus thinking of closing the account and leave. I had Faith in Capitec to help reverse this debit and to stop it please. I'm responsible for the charges not this BESTINTER OR CAPITEC.
