Cell C customer dispute.

Hi. I'm a client of Cell C for years now. Never did I skip any payment until now, where I was forced to reverse their payments for the third month now. It all started when I was called by Cell C consultant who asked me to do a upgrade as one of the three contracts of mine came to an end. I said to her no, I actually want to down scale and close the two lines, the ones that my two daughters are using, when it is done, since I do have unlimited internet connection at home. She continued to ask me to reconsider. I asked her if she could do both the contracts that my two daughters are using, and if so, then I'll do both of them on this R99,00 data package SIM only deal. She checked and confirmed that both can be upgraded to this deal. I then gave her the go ahead if that will be only R99,00 per month per contract, which she confirmed. This is where the problem started. That was in the middle of March this year. The end of April the bill was R135 on the one and R289 on the other one. Then I phoned in to their customer service. Explained the whole story and gave me a reference number saying they will escalate this matter to their head office for further assistance. After a few days I called to follow up myself. Then they said that that reference number didn't exist. I had to explain again, but no luck. Then I phoned again and this time the male consultant understood and explained to me what he saw on the system. The lady who did the upgrade never explained to me that there will be handset fee stool to be paid on the second contract, although there could be a new upgrade be done, until that old contract came to an end at June 8 this year. I then said to him that this was not what that lady told me and I requested from him to revert the contract back to the old contract and to cancel the upgrade. I said that he did do the request and referred the matter to the head office and to contact the client, that's me, again to confirm and also do a cancellation on the first contract, as I requested. From that time nothing happened. Nobody contacted me to resolve the problem. Instead I was called by a lady of Cell C of their accounts department to find out about the arrears on the account. I explained to her what happened and she also apologized to me and said that she will refer the matter to her superiors for assistance. Nothing happened thereafter. Instead they deducted May more money, June again more money and July again more money, of which I reversed all of it. This month again, but no one called to ask me to solve the problem. How can I pay for something that I never requested or wanted or that I was told what it would be and then it's something totally different? Is this how Cell C do business and or treat their clients? I also requested them to stop my contracts, block my lines until the problem is solved. I have sent them many emails and called them time and again, no luck.
