Signal

Dear Cell C,<br> <br> When will your signal actually be good enough so I can cancel my contract with my current service provider? I use a Cell C sim, which is on contract on my dad's name, every month I get 100 anytime minutes and 100mb data, but I can't use it, I never have signal and when I try to call from that sim the person on the other side can't hear me, regardless of where I am in South Africa, I have even switched handsets, but no joy. Due to this I had to take out a contract with another service provider, but I am fed up with their strikes, bad attitude and empty promises. I am impressed with how I never have to wait to be helped at any of your branches and your when I get a call from you guys, nobody shouts at me. However, the signal is a big problem.
