Not doing all they can!

We have no signal at our new home, I phoned Vodacom to query this, after receiving a call from the signal department, I was told that they will be doing an upgrade on one of the towers in our area at the end of April, I totally understand that the signal is under pressure. A booster will apparently also not work, my problem however is that I am a student, I rely on internet (Vodacom Modem) to complete tasks and tests and my partners work is of such a nature that he has to be available 24/7. They can't give us an answer on when the signal will be better, also no answer on when a new tower will be built, the only thing that we are sure of is that there is no signal and that calls keep on dropping. Is this the best you can do Vodacom?
