Reliance Fresh — Bad quality food product

Address:

Kolkata, West Bengal

Hi, Myself Roshni Hari have brought Gathiya (Brand-balaji) from Reliance fresh (Reliance retail limited,477,Barasat Rd,HB Town,Sodepur,Kolkata-700110) , but the food item on opening resulted into foul smell and bitter taste. When I tried to return the item to Reliance fresh they told me that return date of max 14 days from purchase date have been crossed and we can't do anything. My question is what should the consumer do in such situation.the item is still within expiry period and we can't taste all food within 14 days period. Why should they not taking responsibility of selling bad quality producrts. I need proper justification for the same and exchange of my bad quality food product.
