Can't reverse unauthorized debit orders

I have debit orders going through my account and i haven't authorised them, i then contacted capitec via email as I can't reverse them on my app as if the debit order doesn't exist, i have had no response from capitec at all...your service is disgusting, if you decide to handle our monies that we depend on to feed our kids the least you can do is care that we work hard for. I want my money back and trust me! I will switch banks, you are ***** and disgusting
