Vodacom down for days at a time

I have a property in Pearly Beach in the Western cape. The whole village have had bad signal for the past 3 years and from time to time, our service is down for 3 to 6 days. When we report this, We do not get any feedback and Vodacom is extremely slow to follow up. Our business is dependant on 24/7 phone connection. It seems that if you live outside the big cities, you are just not important enough for Vodacom to support you.
