A below Poor Service by Capitec Bank

With my little poor hard-earned cash, I trusted Capitec Bank with my little poor money. There is a debit order that went into my account by the name of 'Bestintern' (BI***3-2) on the 15 March 2021 - The debit order can't be reversed via app and branch in Khayelitsha. I real 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!
