Vodacom leaving emgwenia waterval boven without services again.

It has been a week and a half now in emgwenya watervalboven that vodacom has no signal. There have been cases in the past where we had no signal as well. They made promises to improve this, but they are nothing more than empty promises. They expect a full payment at the end of the month for services they do not deliver. There should be a clause in the contract that would allow you to pay them according to the services received, because this feels a lot like breach of contract and ***** on their behalf. Expecting payment for services not rendered is called theft last I checked.
