Bad qualities of food products in Big Bazaar

Hi, this is manish kumar yadav resident of kolkata on 9th of august I went to buy some food items in bigbazaar I bought several goods I dnt ve any complain regarding other goods but iam really very sad about the worst quality of snacks I got from bigbazaar I always like to have britannia 0-50 maska chaska IM using this biscuit from a long time so on 9th of august I also took some maska chaska packet and whn da next day I opened the packet to eat it was horrible one can easily make out that may be the biscuit has been expired or waste items are getting in bigbazaar these days the colour of the biscuit was different I just want that some action should be taken to remove these types of practices........
