Vodacom Network Coverage

I have 2 Vodacom accounts. For almost 18 months now my Vodacom line is of no use in Hoedspruit. There is no reception regardless of how close you are to the the towers. I will be cancelling this contract and going with MTN. No use paying for something I do not have. Now it seems I have intermittent Network in Johannesburg. None whatsoever the last 2 weeks in Bryanston. Cannot make or receive calls. Cannot even connect via my data. Yet funny enough I run out of data before the month is out. This is not acceptable. The reason why we chose Vodacom 4 years ago was because their coverage of South Africa was the best. Now I am lucky to be able to make any calls.
