Cadbury India — Defective/rotten

I purchased one Cadbury Dairy Silk for Rs 125 and another Cadbury Silk Roast almond for Rs.55 from an outlet called as Grand Bazaar at Minjur, When I opened it after reaching home I found that the packing had shriveled ,melted and not smelling of Chocolates.I returned it to shop who first refused to look into it saying that these 2 pieces were manufactured in May2013 where as the date of sale is[protected]. He has refuse to replace it immediately saying that the product has to be inspected by the Cadbury representative and has collected the same.Till such time I am deprived of my Chocolate. I am holding the original sale bill no.51252 dt.[protected] and the acknowledgment of return of product to Grand Bazaar,Minjur 601203. The shopkeeper has indicated that replacement is not certain. The chocolates were manufactured in May 2013 and the product has not been stored under ideal/hygienic conditions thus the quality of the chocolates have deterioted . I expect immediate replacement and a fair compensation towards my travel and deprivation of pleasure of eating chocolate. Thanks
