Vodacom - Incapable of providing decent signal

We run a small business on the N4 in Waterval Onder where the Vodacom Tower is 300m from us and we are regularly without signal. Today we had to drive 25kms to get signal in order to report the issue and then were still told it could take 7 to 10 days to resolve. If I am not mistaken, Vodacom should be providing signal along the national roads, the N4 being one of the national roads and I can point out at least 3 places in an 80km stretch on the N4 where there is absolutely no signal. South Africans are up in arms about the lack of service Eskom delivers...well let me tell you Vodacom is worse. At least with Eskom you know when the power will be out and for how long, with Vodacom you never know when or for how long you will have no signal.
