Failed to offer customer added value option on upgrade

I upgraded my old Mobile for a new Samsung Note 8 - I enquired about any added value options and was informed there was nothing, a week later I found out there was a option to get a Samsung watch, I went to the store to enquire and was told by Sylvia sorry to late go buy one .... my answer was you never informed me of my options.. reply again go buy one cant help you ... I leave this thought with you .. what next hey so sad - Thank goodness there are other reputable Dealers around ....
