Vodacom Upgrade

I have been a loyal customer of Vodacom for 15 years. I have a 24 month contract and have been notified that my upgrade is due. I went to one of the Vodacom shops only to find out that on their system I have no finance plan and dont qualify for a deal to upgrade my phone. They deduct my account every month but yet their system shows that I basically have no contract with them! I have been promised many dates that this would be sorted by and this still hasn't been resolved. I am not aloud to cancel my "contract" until August yet I according to them I dont even have one! Vodacom is the most expensive service provider but they provide the worst service! I cant wait for August to get some proper service from a more cost effective provider!!!

15 years of being loyal, this is what you get!!!
