False Advertising of a Product

Over the years I have enjoyed going to Spur but, recently I have found two Spur Steak Ranches, Kimberly and Vredendal, when my wife asked for a Passion Fruit and Lemonade drink; she was informed that they use Sprite and claim they taste the same which is not the case. the advertising and selling of the drink as having Lemonade in the mix is false and I find this unacceptable. I don't know if this is a Head Office policy, if so they are deceiving us as consumers. You can take Sprite and Lemonade you can distinctly taste the difference, if it was the same then why would the Products be sold under two different names. Shame on Spur you can do better
