Disgusting debit orders

In the beginning of January 2022 this company debited me with R2600. After many investigations it was confirmed they double debited me. A refund was initiated. Then come end of January 2022 and these people debit my account with R3700. This was after they acknowledged their mistake. If I go I to my billing on vodapay, it says" Thank you mam, your account t is up to date, keep it going". What the hell . I have sent numerous emails to a person called Boitemelo. It is never answered. I am disgusted by the way this company debit people, after they admitted their mistake. The next month, the person liking to hit the debit button just goes forward without investigation as of the client's history. This is what legal people would call enrichment. I am 99.999999 close to stopping this service, as I do not need it.
