CELL C Lying to clients and not assisting them

I’ve been phoning cell c customer care and contract department for 2 months consistently everyday asking for assistance so I can receive my paid up letter. I spoke to 2 team leaders who I sent the proof of payment to as well as the case numbers they both did nothing but say they have escalated it, I've sent mails to credit queries with the proof of payment and I’ve logged 3 cases every time I call they are not able to give me answers instead they tell me to redo the process again and again.I have tried to be patient but I think it’s time cell is exposed for what they are doing to people in this regard.Today I went to a store to contact head office and I was still not given proper feedback instead I was told that they are looking into it. This is unacceptable and it seems as though Shapiro shake and cell c are working together to intentionally provide people with the incorrect information as I believe they have given my number as a lead to other legal firms which call me everyday saying they can assist me to get the paid up letter. what’s even more disappointing is that the consultant don’t know how to handle the situation instead they say you should redo a process that clearly isn’t working.
