No Vodacom signal on the farm

About 2 weeks back I contacted Vodacom about my problem of no signal on the farm where I am staying. A complaint was logged and investigated compared to them, the complaint was closed without a solution. I am sitting without signal for about 3 and a half weeks now. By this I mean no signal at all, I have a few Vodacom numbers. My son and father in law all have Vodacom numbers. Every month I must pay my full account but I have limited use from my service provider. I have asked Vodacom if they will take responsibility if something happens on the farm and I or we can't contact anybody. They admitted that it is a big concern but nothing is done to resolve the problem.
