Vodacom fails to deliver

I've upgraded both of my contracts with vodacom and experiencing problems with both of them. The consultants don't listen to the requests of the customer and I end up with contracts that was not initially agreed to. I'm also working in Cullinan at the mine. In town, where I rent we struggle with signal daily but when I'm at work we have signal. Vodacom can cater to the needs of big businesses but fail to deliver good services to the man in the street
