******** debit access

I have been a Cell C client for many many years. During December 2022 they breached our contract and debited my account on the 22nd instead of the last day of the month as agreed upon. Before payday, they tried debiting two more times. I pay R105 per transaction that is unsuccessful. Who will now be paying this?? I contacted Cell C and made an arrangement for my debit order to go off DOUBLE on the last day of January 2023. It is now the 15th January 2023 and they decided to debit my account today. Hence, I HAVE NO MONEY TO SURVIVE THE REST OF THE MONTH!!!!
