Amul / Gcmmf — bad and fake assurance of the products (curd)

I purchased 1kg of amul curd on 15 july by date and then founded that it smells very unpleasant and recognize that it tastes really bad, then the real ordinary curd taste and further on the pack their was return that best before 15 days o[censored]se and the packaging date was just 12 july so is this your 15 days validity or are writing these things for just faking people's. I am getting this defect for 3rd time. At the 1st and 2nd time founded that it might happens in once or while but only this is mine 3rd time i founded to talk over it so... If really want that amul should be a brand as it was earlier at least be real instead of been fake.
Only because amul is a company from early years and gives the quality assurance we people on yours assurance put faith.
