Horrible Network Connection!!!!!!

I live in a township called Evaton in the Vaal Triangle and I hardly have network connections. I upgraded 3 months ago and to this day I regret upgrading with Telkom as the network coverage is extremely poor for the past couple of months. What is the whole point of having/paying a contract when I hardly use my cellphone when I'm home??? I use my cellphone when I'm at work because of the WI-FI connection but when I get home, it's a totally different story. How is it that other network providers, their connection is good and not Telkom?

Telkom needs to do something about this..... Every month when you debit, it's a pain in my heart!!!
