Bad Network Signal Ever

I have been MTN customer since 2003, when I had my first cell phone. But I have never felt so much pressure to change network service provider like I do now. I feel MTN is dying slowly as people are compelled to change service providers due to the poor network signal. I stay in Riverside View in Fourways (Gauteng) and I really struggle to access internet and social media. Above this I have zero access to the MTN network when I am home in Eastern (Jenca Tsolo - Entywenka). The sad part is I am stuck with MTN till the end of my long MTN contract.
