The courier guy - no responsibility for broken parcels delivered!

I couriered a parcel, a large flat wooden decor parcel. Wrapped sufficiently to the rules of courier guy and a fragile sticker added (also their rules, no fragile sticker, no claim)

My parcel arrived in a terrible state. The item was made from Superwood - the strongest wood you can get. Due to their handling, it arrived completely broken. Not just a scratch broken. Broken!

The courier guy refuse to let me put in a claim for this item. Now, if i wrapped it to the rules, put a fragile sticker. Why is it my problem, that my parcel was delivered broken? They don't want to answer that part though, they only focus on, it is not their problem.

I have photos of the my parcel and the state it was delivered in, which was also sent to the courier guy to review.

I welcome someone from The courier guy to please resolve this in a responsible manner.
