Covarage issue

We moved to Bela-Bela in July. Mid August we started complaining to mtn regarding the bad signal. We were told that they are busy upgrading a tower close to us which should be done by the end of September. In September we complained again. We were told that the supervisor will call us. Needless to say no one called. Ever since we started complaining we get no feedback from nobody. We called again and said that seeing nothing is being done about the issue we want to cancel all our contracts effective immediately. We were told then we have to paid a huge amount of money before we can do that but they will get back to us. Still no response. Comes end of October we get billed for things we did not even use. But still the signal issue goes on.
