Cell C incompetence and still no answers

We have had our Cell C router for 6 months. Out of the six months we have paid for six and used two. We have had the router send in for repairs. Got new paid for sim cards. Had software updates and and and and. If we do not call, nobody will. If we do not follow-up. Nobody will. We have spent hours in Cell C shops, been sent from one branch to the next. Still no answers or help. In between that my cellphone got damaged and we took it to Cell C for either repairs or replacement on our insurance. Two weeks later after we had to follow up with calls from Cape Town to Johannesburg we were told that the claim was cancelled. So who cancelled it? Nobody new. Once again back to the Cell C shop to find our original papers and resubmit it. Still no phone call and I have no idea when I will have my cellphone back. I work from home so I had to go out and find alternatives for work wifi and phone. We wanted to cancel our router and data but will have to pay for the cancelled contract - the fact that we have not used anything for 4 months because of Cell C not withstanding. We have six contracts with Cell C. We will not be returning.
