Poor to non existant service From Vodacom

Again no signal from Vodacom, this is now ongoing since March this year. All our complaint fall on deaf ears. Nothing is being done about the poor network performance in our area. But still, I must pay my full bill for a totaly substandard service. I'm going to stop payment to Vodacom as from the 15th of this(September 2024)Vodacom clearly doesn't want to fix the problems on their network. Again, there is a contract between me and Vodacom, I pay and they must deliver the service, if I don't pay, I'm deemed to be in Breech of contract, but in this case Vodacom is in Breech of our contract as they don't deliver the service I'm paying for, and seemingly refuse to fix the network problem. I'm done paying for this unreliable service. I'm going to stop payment because Vodacom is breeching our contract, furthermore, I want Vodacom to cancel all of our contracts(the amount per month is about R 2000)and I'm not willing to pay that king of amount for a substandard service.
