Poor network signal in Jhb

The Cell C network signal has been very poor in Bryanston and for the last 2 years (when I joined Cell C). I was told by Cell C to change the settings on my phone to ***gy-back onto the Vodacom network but that did not help (the Vodacom signal on my tablet is markedly better, so it's not a Vodacom problem). The Cell C signal has become worse in the last week. Downloading e-mails and opening webpages has always been slow but now I cannot even download e-mails or open webpages at all!!<br> <br> Cell C should stop making promises and spending money on buying out other service providers' subscribers' contracts and spend the money on improving Cell C's network coverage and signal quality. That way Cell C won't have to \buy"customers"
