worst cellular network provider ever

For the past week my whole family has had almost no signal. This is pathetic as i am paying a lot of money for my contracts every month. I often have to stay at home alone and would like to know that when i have an emergency i can atleast get hold of someone but unfortunately vodacom makes that impossible. If i knew that vodacom had such bad network i would never have taken out a contract with them. I wont recommend vodacom as a service provider to annyone. The worst is that i am now stuck in a 24 month contract. This is very bad
