delayed flights, damaged goods

Worst expirence fly on domestic flights with BA.Eepature flight delayed by 45min and return by 2 hours!To top it off I had an item checked in as fragile which was clearly marked fragile and checked in at the fragile counter.It was clearly mentioned on numerously that the item was glass.On my arrival the item comes out as normal luggage instead of fragile and off course, the item was broken.You could also see that all the fragile stickers where torn off.It has taken over two weeks to try and get some sort of feedback.Instead all I keep getting it a snippet from saying that you are not liable for damage.I would accept that as a reason if my item was handled as fragile but clearly this was not so.Another guy on our flight also had fragile items checked in.However when he received his item,he was handed it by one of the staff.So my question is, why was his item treated different to mine!The lady dealing with my case was to look at some camera footage and get back to me.However, a week later I can not get in contact with her. When I called the BA a 2nd lady assists saying that BA is not liable,no one can tell me what really happened and there is no feedback on any footage to be viewed!
