Waiter conned us with regard to pricing!!!!!

My family and I went out to dinner on the 28 March 2016 for a relatives birthday celebration.<br> We were told that a certain drink would be cheaper if we had ordered a pitcher. We gladly took the waiters advice and bought four pitchers of Passion Fruit cordial and Lemonade. We were told that it would cost R30 per pitcher. We paid the bill only to realize that we were charged R95 per pitcher.<br> I was very disheartened upon learning that I was **** to by an employee of such a reputable restaurant.<br> I sincerely wish that Adega makes up for the mishap.
