Bad customer service

I'm complaining about DSTV because even though I have a credit in my account of R1400 for the DSTV Family package and I called in daily since the 03rd February 2023 so that they don't do a debit order from my bank account, today I saw a debit order went off. I spoke to Jazzmin Saydom who confirmed the banking details and said I should call on Sunday to confirm the money was received. Today they not only deducted the wrong amount from my account despite confirming that the R1400 reflected in my account but the amount was also wrong. Nonkululeko confirmed a supervisor would call me back in 15 to 20 minutes because she herself couldn't give me correct answers. No one has called me. This is terrible service!
