[Resolved]  Amul Processed Cheese — found rotten and smelling

I bought a packet of Amul Processed Cheese From VISHAL MEGAMART 10 days ago, Mfg printed : MAY-08 and expiry is after 9 months from the date of manufacture, Barcode No.[protected], when we opened the packed It was found Rotten and Smelling and to our surprise we found our small kids were having one in there hand and were eating the same. When I went to Vishal Megamart raising this complain, they refused to accept that product without bill, but after lot of discussion they agreed to take our complain to higher authority. But i am not satisfied with their step as I only want Amul Company to check the whole lot and thier manufacturing and packaging process as well as the quality of raw materials used for that lot, so that this kind of negligence can be avoided.
I have always loved AMUL products from my childhood, but this incident has hurt me.
