worst company ever

I have been having issues with them since June. I have posted them on hello Peter and up till now still did not get a call from them. I was canceling with them before I did my move as I was not getting the proper service, they begged me to stay, they could not solve the issue so they said I must make a new application again. Im still getting terrible service, being double billed. I'm trying to cancel and I can't even do that as once again the app won't allow, this was the reason I had issues in June. IM IN THE PROCESS OF CANCELING, now they want to charge me service fee and installation fee like I'm a new client which is round R 4000 to R6000.
