i recently bought 500ml sting flavour was change then i look at bottle and i saw bottle neck

bottle neck was little higher then regular one i buy normaly ithought it might be mistake from production and the other day i was near tower i send my friend to buy sting and then i found same pattren bottle name lable was change it was storm if it is also belong to pepsi  i thought but product was made by mezan and it is fake my request is plz do take action against those shopkeeper whom are puting it in pepsi freezer  ,because most of customer see that red color bottle and take it after that they miss that delicious flavour and then never buy it because of flavour changing !
