Audi dealer in Jacksonville steals gun from customers car

My daughter was in from out of town and needed service on her Audi A4. She is a traveling nurse and carries a gun for protection. She purposely locked her gun in the glovebox of her car, but upon leaving the dealership, she noticed the glovebox unlocked and her gun missing. Upon contacting the dealer, the service manager, Janet, was rude, unprofessional, and extremely defensive. She wound up saying we could not prove anything, therefore they were not liable.
