Cancellation of Contract

I have been in contact with the coverage department for a few months now. After them telling me it will take 18/24 months to put up new signal towers, I asked what were my options. They told me to contact MTN and cancel the contract due to coverage issues and move to a different network.<br> <br> I have contacted MTN and after going back and forth with them they want me to take it up with the coverage department. Nobody knows what they are doing and what they are supposed to do on either side. <br> <br> I need feedback asap as I am paying for a contract for nothing, the signal is terrible.
