Britannia Industries — Milk Bikis - biscuits are eaten by rodents

It was noticed that the Milk Bikis packet had many biscuits eaten by rodents or any other pests. The pictures and videos are sent for reference.
I would bring to your kind notice that if this biscuits were consumed by children or any other in my family what would had happened.
Luckily we noticed and did not consume.
With much more difficulty I would state that the packet was not opened but the biscuits were found in such condition. Else I would have approached the shop keeper. It was found that the defects in biscuits would never be seen since the packet was unopened.
