Mcvitie's — adulterated biscuits

Address:

Sirmaur, Himachal Pradesh, 173030

I purchased mcvitie's wholewheat marie biscuits from dmart 10 days ago. Yesterday i opened one packet which has a foul smell like paint or fevistick. I've kept that packet as a proof and i want strict action to be taken against the company. I used to like mcvitie's but after receiving a packet like this i don't think i'm ever going to buy it again.
