Head office says one thing / branch says another

Im due a upgrade And honestly I cannot understand the arrogance of Vodacom I recently contacted vodacom via Facebook showing them a mtn catalogue deal which beats vodacoms current iPhone 6s offering , the response was that I should go to a vodacom store and produce this advert and the store would then match it , I went through to pavilion branch recently and I was told by a consultant that it was just about pointless for him to send through a price match request to his head office he explained that vodacom head office will not consider someone who's only been in contract for two years and he said that they would only consider a higher paying contract customer , this has annoyed me very much I have two contract withs vodacom currently for my iPhone and iPad , I pay over 1000 rand a month according to this consultant it would seem vodacom deems my business, my 1000 odd rand a month as petty , the arrogance is shocking given cell c Is *****ing customers right from under vodacoms nose with thier contract buyout incentive . It's bad enough vodacoms deals are not near close enough to thier competitors and to be told the store would match and then to be told otherwise is disgraceful
