Unauthorized Absa debit

This is the second month that I am getting unauthorized debit orders on my Absa account. The first one was from a company called Royal Mark, which debited R115.00, I reversed it at Mall of Africa, after which a company called Taylin debited my account twice with R95.00. I really find it absurd that Absa still allows companies to randomly dig into personal accounts without following the correct authorization channels. How is it that after so many complaints from different people, they still have not taken a substantial step to rectify this issue?
