US Airways Damaged my ski equipment while loading plane and not wanting to be held responsible Pittsburgh Pennsylvania

I went on a ski trip to Swizerland. One my way back from Zurich my ski bag was torn open and the my ski equipment was damaged. I went to customer service to file a claim. The lady entered the claim in the computer system. The lady started getting an attitude just like the rest of the US Airways employees I experienced on this trip. Then she told me that US Airways may not pay the claim for they aren't responsible for damaged articles. I was very upset with the fact that the bag wasn't torn before I left Zurich; and US Airways refused to be responsible for their poor baggage handling. At that point, I was too upset so went to get a security guard to have him see the damage on my bag and ski equipment. The guard even said he would be upset too when he saw how badly the ski bag was torn. I told the lady I will never fly US Airways for several reasons. One, I didn't like their flight attendant service (grumpy people); two, the fact that they aren't taking responsibility for damaged goods that was done by US Airways employees; and three, the lady I was filing a claim with make me look like I was the bad guy for being upset to the guards and other US Airways employees! Personally, I wouldn't recommend flying US Airways!!!!!!!!!!
