Vodacom technical service sucks!

Since the beginning of October 2109 we have had a problem with signal at our office. We originally had a cellvine extension aerial installed by vodacom as there is poor signal in our area and then another one a few years later. It seems that this one is also faulty now. We have contacted Vodacom and been promised to the point of contacting their CEO in December who promised to sort out the problem. Still nothing has been resolved. We are losing a massive amount of business and Vodacom couldnt care a hoot!!
