Pall Mall / 25g tobacco pall mall

I bought a 25g of pall mall tobacco from the cooperative food store in Cheshire today and when I got back into my vehicle I felt the pouch and it was rock solid. So I further investigated it and looked inside and all the tobacco was solid together. When trying to separate it it just crumbled into little bits. Thursday 10th November 2016. As I normally get tobacco and the tobacco I always buy is pall mall I expected it to be of standard as I normally know, but for some reason it was not this time. I know the consistency should not be like this and I am very unhappy with the product. The product when first bought from a shop should not crumble into what can only be described as coffee granuels. I would appreciate some sort of compensation for this shocking product. Thankyou very much
