Damage of items that was suppose to be in the fragile transport area

I booked 3 bags in Bali at the fragile area. all these bags were locks with locks. when it arrive in South Africa, the baggage wasn't in the fragile area but was on the travellater. When I open the bags at home, I found multiple items broken. Raise an complain to Qatar were I was informed that i should have checked all the items prior of leaving the airport, then a Peter phoned my. He informed me that I 'm not allowed to book in travel bags in the fragile area, only items that isnt a bag are allowed to be booked in. I now asking in why wasnt this communicated to me at the airport to say that bags isnt allowed to be booked in, then i took these bags as hand luggage. Now the airline is just saying I signed a document at Bali stating that the airlines isnt held accountable for damages to fragile items. So if you have a brand new bag, and they broke your bag, it just your problem as they dont take accountability for the damage. Seems they also have uninformed staff that is not communicating the airlines processes and procedures to clients and when there is any damages the client just need to accept the damage. They mentioned that I signed a acceptance of good document, but cannot supply me with this document. I only signed the fragile stickers when items were booked in to state that the bags and items in the bag is in good conditions. Now they making it out I signed documents to say that i accepted the bags that was broken and the goods in the bag was all in good conditions. USELESS will never travel with this airlines, not even if there airfares is for free.
