Bad service from Vodacom to their loyal RED VIP Cu

I was a Vodacom Platinum Customer, I regularly received emails, etc. I phoned the platinum desk on 27th January 2016, and they TWICE confirmed that my new upgrade date is 01/02/2016. When I went to Vodacom on the 1st of Feb, they said no that I'm only a RED VIP customer again, and that I can only upgrade on November 2016. I've been a Vodacom Client for 16 years now and a Platinum member for the last I don't know how many years. John Hopley from Shelley Beach, never called me back like he promised this week and today I learn he's on leave for two weeks. No one at the call centre can help me, what else can I do. This service is terrible to your loyal Clients.
