Signal Issues

I live in Nottingham Road, KZN. Since November 2015 we (many farmers in the area) have experienced shocking signal; some days no signal at all! I logged about 2 or 3 complaints over the Christmas period. Vodacom responded promptly and attempted to address the issue. It improved slightly. We are now experiencing the same issue. I just tried to log a complaint (15 March 2016 at approx noon) and was told, because my contract is a business account paid for by my employer, I needed to provide the account number before a complaint could be lodged!! This is utterly ridiculous and inconvenient!! What is the account numbers relevance to my signal issues?!?! I expect a PROMPT response from Vodacom, and a complaint to logged and appropriately dealt with! The lack of signal is not only inconvenient, but it puts us at risk as our cell phones are the only means of communication in times of emergency, living in a farming community. Vodacom was always known as the best cell phone service. Our experience lately, has been anything but, and we are seriously considering changing network providers if this is not resolved.
