Pepsico India Holdings Pvt Ltd — Expired Product being sold at Retailer

Address:

Mumbai City, Maharashtra

I reside near Mahalaxmi Temple at Breach Candy. I bought TWO pet bottles of Dukes Ice-Cream Soda. When I went home I realized that the products were way past the expiry date. I went back to the store and told the retailer to exchange it but he refused saying he cannot replace an opened bottle. What am I to do with the bottle now? Why is he storing and selling long-expired products of Pepsico in the first place? I don't think this goes down well with the consumer relations of your company.

(Mfg Date: 05/06/2012; Date of Expiry: from 3 months of date of Manufacture i.e. 05/12/2012)

Please do something in this regard.
Thank You.
