CELL C - MOST APPALLING SERVICE EVER EXPERIENCED!!

I have had the worst customer care service from Cell C. I have been struggling to sort out this issues with them for more 2 months now and no one wants to step up and solve the problem. I have changed my debit order date and still they have been putting a debit order through on the original date as well as the new date, but still I have not been able to use my airtime. At the Cell C store in Greenacres it shows on their system that I am actually one month ahead with payments, but STILL I get messages saying that I am in arrears and threatening to give me a bad credit rating. I have asked on numerous occasions to speak to a manager, as I have not gotten anywhere with the Call Centre agents, but I have been met with absolute REFUSAL to put me through to a manager. I am so disappointing in the ARROGANCE that this issue has been dealt with. The Consumer Counsel needs to look into this company and the manner in which they treat their customers.
