No Service, no support. Breach of contract

I entered into a contract with Cell C and Nashua Mobile (this has since been transferred to Altech Autopage by Nashua who no longer operate). The contract states Cell C will provide the service of a network facility which will allow me to make and receive calls, send SMS's and use the internet.<br> There is no signal at my home premises at 29 Greenmeadow Lane, Hillcrest 3610, or at my friends home in Assa*** and in many of the areas I visit. I am mostly unable to make use of the internet unless connected to a local Wifi. Cell C have failed to provide the service for which I am paying.<br> There is no provision for me to speak to anyone in management or at a higher level. Cell C were supposed to send a technician . I made a complaint to Altech Autopage on 19th January 2015, who gave me a Cell C technical fault reference number SD362019. Spoke to Gideon on 19th January 2015 at Altech. Phoned Cell C 140 No. in mid Feb. Phoned again end of Feb and again 5th March 2015, spoke to Pringle and was told complaint was assigned to network technicians would contact me. Still nothing. Cell C can't even call me due to poor signal. contract terms are not being met. Breach of contract.
