Impossible to get Vodacom to address signal outage

Vodacom is going from bad to worse. For years they have been promising to address the signal problem in our area. Currently, we have had no signal for two days and no response from Vodacom. One gets to talk to a bot that is useless and says goodbye! |And in the meantime, our businesses have come to a standstill. How is it acceptable that Vodacom takes money from people and does not honour their contract?
