Britannia Industries — Quality of Product - Overcooked

Have been a fan of Britannia biscuits for a quite long time. But the quality of biscuit have not been same as it was before. The biscuits are overcooked and the quality have decreased as it tastes quite different as it was before.
Previously the cashew was visible and we can feel there's cashew in it while eating the biscuit but now its more of a biscuit. Saw black marks on the biscuit still confused either it was overcooked or what? I hope will get answer from britannia's side of the photo which I am attaching with this complaint and they will improve their product quality in future.
