No signal

been waiting over a year for Telkom Mobile to put a device in my roof to give me signal at my house. I was promised that there was coverage when I took out my first contract, the website shows we have coverage. Have subsequently taken out more contracts with the promise that they would give me a device in the roof so I can make/ receive calls at the house. I have sent numerous emails to head office but they all get ignored.<br> I have requested to terminate my contracts early so I can move to another network with signal but they also ignore this.
