Tired of the lack of security with capitec

Two years ago I had an issue with companies that load debichecks to my account without my approval. I contacted my bank and they managed to sort it out after weeks of struggle. Now I'm facing the same issue. A company called Makanda Finance Hass loaded a debit check to my account twice and an amount of R600 and some went off last month, this month I see they landed again. I had a contract with them which I settled many years ago and I asked capitec to assist me with getting this money back and canceling the Debi and they refuse or say they can't, however It was done two years ago. Also I had a situation where Netflix deducted early and I called in spoke to consultant and he reversed the amount 2 months ago, same month same thing happened called again they said they can't do it. Went into the bank and they said there is no history of a reversal as this is a subscription. I then showed them the text notification showing it went off and came back but for some reason things get removed from there systems making the client look crazy.

I have been with capitec for over 15 years however this is it now. I am a single parent I do not earn much and if my bank can't help me then why am I staying. I need assistance with getting this Debi check off my account and that money returned because I know it can be done. I am tired of the different departments giving different stories.
