Bad customer service

Hi, I'm very disgusted with cell c customer service, it's the second time now I made a payment arrangement but nothing is happening and my bank and cell c are charging me for everytime their system comes to my account and find no money and it will more than six times a month, which last month I lost R1000 and something I called them about this they said they gonna fix it this month it's R3400 and something how do they really expect me to get extra money while am loosing such amounts every month to pay them? Second time within a year this absolutely nonsense as I have with cell c for more than 10 years now. Case no. ***.id *** contacts *** can this be sorted pls. Cause the thing of calling the call center is not working for cause none of them have answers. And superiors of cell c have a nerve to take decisions for customers who pays them without contacting them. Sis this is just pooo!!!
