Fauls advertising

I bought a vodacom 10.1 tab at exact on the 27 November 2015.The onboard memory advertised on the internet, brouchers and the tab box is 8gig but the memory on my tab is only 3gig. I went to the store and they sent me from pillar to post. The lady at the store phoned someone they said is from either Vodacom or their technician who told me that the tab is fine that half of the memory is used by the apps and if I need all my 8gig I have to delete all my apps on the tab. That would mean I need to delete apps like camera , messages internet browsers and all the vital apps. That is nonsense! Where in the world have u had such *******? All phones have apps and the advertised memory is excludes the apps. Even memory cards have folders already installed but the advertised memory isn't affected. <br> <br> When I explained that the guy told me that they were just informed in their meeting of that problem and he would come to the store the following day to check the tab n the store was to contact me afterwards. Well I am still waiting for the call<br> <br> All I want is to be refunded so I can go buy a tab from a reputable outlet with honest advertising.<br> Please take accountability and deal with this!
