Vodacom poor services.

I'm a Vodacom customer for a very long time now. That last couple of months we the people in Olifantshoek Northern Cape struggle with Vodacom signal. If you phone in it's the same story, now one reported the problem, yet many people phone in the same day to report the problem, (we have to went 50 km out of town to have any signal) that is if you can get hold of anyone. This week alone we went a couple of days without any signal. I pay over the R2000 a month for 5 data bundles. If I have no signal I can't do my work. I have a 24/7 road assistance business. Can someone please explain to me why? Why am I waisting money on a company that can't comply?
