Cell C ****en *********** top management

it's been over 7 months contacting Cell c regarding their network issue, they did however come to my place and told me that they will come and install a booster. After a while when I call them they tell me that they came to my place and didn't find me and when I asked them on why they don't answer. And now no one is willing to tell me a way forward and when I request to speak to management Muhammed since he promised to call me back to date he hasn't. I Had anot opportunity to speak to Thabo Mokoena whom sounded rude and *********** and dropped my calls making promises that he didn't keep.He doesn't want me to speak to Morne Devel and or the Cell C CO Jos? Dos Santos or someone in charge of customer care as a whole. I'm tired and ****en tired by this I hope this get to the desk of the Ceo, I really would like to have a word with him. I was also promised by Bonisiwe Ngina that I won't be charged for default charge fee of R70 for January but now they have charged it and my line has been suspended without my queries being resolved.SSipho May the escalation team leader also dropped my call telling me that it is his time to go home and promised to call me back To date he has not.c
