Vodacom - Time to step up!

I have two data contracts with Vodacom but the reception is pathetic. It is constantly unpredictable. Although it says that the strength is strong and it shows 2-3bars the internet comes and goes at will. Over the weekend we have had no internet at all. Most disappointed. On the 29th September we received an SMS telling us that "Vodacom has improved the network infrastructure in our area" but now its got even worse. This needs to be sorted out very soon. I am already dreading December when the holiday crowds arrive. Last year we had no Internet at all from the 15th December until 5/6th Jan. We are paying for a service that does not exist. Time to pay attention to your loyal subscribers and fix this mess.
