CELL C NETWORK COVERAGE

We have been with Cell C for the past 11 years, and never experienced any problems up until the past 7 months. At first I thought it was my device that was old and not working properly but I purchased a new phone about 5 months ago and still the same issue. There is just no coverage in Vanderbijlpark. No matter where I am, I'm always struggling to get onto the internet, Facebook, Whatsapp ect. I waist away all my data just to try and log in to Facebook / opening a internet site, let alone facebook-ing or browsing at all. This is really unacceptable. Very disappointed in Cell C. I will be changing over to another service provider come April with my upgrade date...
