Appalling service continues at cell c

Bad service is a norm at cell c, I wrote a review a week ago, someone promised to get back to me, I still await for some to call me even today.. typical of cell c. In trying to resolve my issue with Cell C today i contacted Cell C, and in turn the lady handling my case called me back Melinda Dlamini, she spoke to me with the utmost arragance, wasnt willing to listen to anything I had to say, I could tell her whole point of the call was to put me in my place, even after i humbly told her over and over again that i don't appreciate the tone she is using, she continued on her path of shouting and ranting. she also acknowledged that their sales department issued wrong contracts, now i must be penalised for that. I have picked up what the issue on my account is, but because of her arrogance she hasn't heard what i have to say to her, and investigate what i am saying. It would help she would just listen to me with no attitude or arrogance, there seems to have been another account opened that i was not aware of, but she just explains that away with some lame excuse and doesnt stop to think that i might have been billed wrongly. I had a fibre contract with cell c, she sends me terms and conditions of a cellphone contract to try and prove their claim, and doesnt want to hear when i tell her that is not the terms and contract i received for my fibre contract. Towards the end of the call when she was done with her ranting she seemed disinterested, and just send "send me email with prove". Appalling service, spent about 5 minutes on a call with a her and she did'nt hear a word i was saying to her.
