Vodacom - WORST cell phone service!

We have a business in the CBD of Nelspruit (the capital of Mpumalanga(!)). When we moved to this premise 18 months ago, we realized that we do not have Vodacom signal on our premises, IN town! After numerous requests to Vodacom, their own technician came to our premises and acknowledged that the signal is very bad here. The options were stated to us eventually: buy your own Vodacom booster or cancel your contracts(!). Just like that. Combined we have business Vodacom contracts of about R12,000 per month, just among the directors. "Best network", NOT A CHANCE!!
