Nandini Milk — Nandini milk smells bad

Hello Team, Please be informed that nandini blue packet milk smells bad and contains chlorine and bleaching powder aroma since a month. It's too hard to consume it. Even children are stopping to consume the milk.
Request to take immediate action towards the issue. I hope i am not the only person complaining on this same issue.
Immediate attention towards the issue is much appreciated.
