Mother Dairy — mother dairy cow milk

This is to bring to your kind notice that i always buy mother diary cow milk from our nearest mother diary booth at new alipore, kolkata, west bengal. But this time i am really disappointed. I purchased 3 packets of 500ml cow milk and it smells like bleaching or any other chemical when i boiled it. I think there is chemical in that milk. I almost felt like vomitting when i smelled it. I never had such type of experience before. Please look into this matter. This is not acceptable at all. Milk is our basic need and this matter is really serious.
