Purchased a 2l sprite full of water

<br> Very dissapointed customer, we purchased 12 bottles of 2l Sprite Zero from Seadoone Mall Checkers, needless to say when we opened one of the bottles it was filled with tap water and closed very neatly. I am sorry but this is ridiculous, does this mean that I must check every bottle of cooldrink every time I purchase from your store??? If I wanted water I would opened my tap.
