Unresolved query

I am so frustrated, I don't know what else to do, I have been trying to sort out the issue with cell c but I'm not winning. My account we with cell c was in arrears for 2 Months however I paid them R2200 that was owing, I paid them on the 4th or the 6th of Jan 2024 if I'm not mistaken, on my statement it shows that I paid them on the 6th. I used the cell c app to make a payment because I didn't have their account details however My cell c account was not adjusted after I have paid them, I thought that maybe there's a delay, but what was surprising is that they kept debiting my bank account every week for the same amount that I have paid , and those debit orders kept coming back due to insufficient funds, and whenever that happened I got charged an unpaid fee of R105. I then went to the branch with my statement to try and sort it out but they just adjusted the balance due on my cell c app, my line was still suspended and the debit orders were still coming through. I contacted the customer service and sent emails a number of times but I still didn't get the help that I needed. They are not able to trace where the money is . The last feedback that I got from them is that they have paid the money back to my account but there is nowhere on my statement where it shows that the money was paid back. Their systems are failing them and I have to pay the price. I need a refund of all the unpaid fees that I have been charged after paying them and I need this matter to be sorted out as soon as possible because now I'm not even sure if I should continue to pay my monthly installments, but even if I do, on their side it will still show that I still owe them. I want to do what is right but they are making it difficult for me. The following are all the Ref.No. received from Cell C every time I logged a call. Ref.No.*** Ref.No.*** Ref.No.*** Ref.No.***
