No response after 4 weeks!

I logged a query online (ref 007V~VNG8 ) on 27 March 2015 and is still waiting for a reply. First you force customers into a price increase with now way to fairly get out of the contract and then you don't respond to queries! What is happening with Vodacom. After being a customer for over 15 years, I really think I should find an alternative SP when my contract expires as you lately do not seem to give a damn about your customers, not to mention the customers that have been loyal for many years. You should be ashamed of your apauling customer service.
