Unauthorized Debit orders

My son Sabelo Mnikati have been experiencing debit orders that he had never authorized from Sanlam. They have been debiting from his persal since November 2024 and at Feb 2025 they have added another policy. I gues there would be 10 policies added by the end of 2025. Such a ***** company I have never seen

I want them to cancel and refind my son with immediate effect and stop their nonsense
