Reliance Fresh — Fungus on the item purchased

Dear Sir/Madam,

I'm very sorry to say that the Name of your store "Reliance FRESH" is not worth as there's nothing fresh in it. Today, being Sunday we went to Reliance fresh Store in Sector 28 Faridabad to purchase the grocery items. We have purchased one Amul Shrikhand Elachi flavor mfg. date mentioned on the pack was 02/09/09, expiry date as mentioned on the pack says after 6 month from the date of manufacturing. But when we opened the pack it smells very bad and there's all fungus inside the pack.
My complaint is how one can be so cool after seeing all this. It’s a matter of one's health. I know that we are having 2nd in terms of population, but it doesn't means that one can take liberty of harming someone else's health. Moreover it’s also not about money (50 Rs) it's more than that. If sm1 stole your money what one do and what's the punishment? You all know but here we are talking about more than that i.e. someone is harming our health. As a popular saying says "Health is wealth". My question is what should one do to stop all this, where will be the listening and what will be the punishment?
Hoping that an early response will be provided and can satisfy me.
