Cell C Accounts department is USELESS and non existing have been Complaining since Oct 2021

In 2021 there were 6 payments that were made on my cell c account that cell c did not pick up because we used an old reference number, since October 2021 I have been phoning and mailing cell c the proof of payment and then calling into the call centre where I then mail the consultants the POP and so it went on and on and on, in December after the line was suspended for about a month I had enough, I called and asked to speak to a supervisor, I explained the situation to then and told them that this was the last, if the cell c accounts department can not do their job and allocate the payment that I have been sending to them for months then I will cancel my contract, within 24 hours the line was active and I thought the problem was solved. On my January statement, it looked like the problem was solved. The only problem I had was that cell c kept billing me for failed debit orders even thought it was the cell c accounts department that did not do their job and allocate the payment since October 2021. So, I mailed the customer service department and explained it to them, one of the consultant called me to confirm that the problem was the unpaid debit order fees that they need to reverse on my account, I agreed and was very happy to hear that this nightmare would be over. BUT NO, then I get my February statement and I could not believe my eyes. the problem is still there. The reversed evey single payment that was reflecting on the statement. I called the cell c help desk and the collections department picked up the phone, everything in this complaint I explained to the consultant and she told me she can not assist me and will get her manager to call me back the same day (9th February 2022) it is now the next day MONTHS later and no one from cell c has tried contacting me on any of my numbers.
