Be clear about the fine print

I pre-ordered a Samsung Galaxy S7 about 2 weeks ago. the delivery of my device was confirmed telephonically and via sms. When I arrived at the store at 17:32, I was required to wait more than 90minutes to be assisted due to the store being \short- staffed\", which I did.<br> when I was finally assisted I then experienced 2 major issues:<br> 1. the VR GEAR that is promised in the advert is not given to me, instead I am told to register online and wait for Samsung to deliver it. This is NOT EXPLAINED when u place your order and neither is it in any of the adverts.<br> 2. The technical assistant couldn't help me because he was \"too busy\" and had worked an \"11-hour-shift\". so the fact that I waited nearly 2 hours by that time didn't matter to anyone in that store.<br> on a side note, when I asked about comfortable seating (as my back was in immense pain as I suffer from kidney failure) I was placed on a seat with a backrest by 1 of the staff...only to be unceremoniously kicked off the seat by another vodacom staff member in the branch. I dont expect feedback from vodacom as I have requested feedback in<br> the past with no feedback forthcoming. I suppose that when a business has that big of a market share"
