No signal and their resolution is pathetic

We all of a sudden have no MTN signal in our house, approximately 5 times a day we have the message \emergency calls only\" MTN solution, install an antenna in one spot in the house and when you need to use your phone attach the antenna to it. How is that a solution I work from home and already have a fixed line, now my mobile phone becomes a fixed phone??? I contacted autopage to advise I want to move to Vodacom only to be told I have to pay a cancellation fee??? This is ridiculous MTN cannot provide me with a mobile service so why should I not be able to change without a cost?? "
