Freebird Airlines Damaged My Suitcase and Refused to Replace It

Freebird Airlines damaged my suitcase during the flight and refused to provide compensation. They are demanding an invoice for the suitcase, but I am unable to locate it. Even though I provided detailed information about the suitcase, including photos of the damage, they still insist on the invoice. They have not offered to replace the suitcase, and now I am forced to purchase a new one, which costs significantly more than before. This unexpected expense has caused me considerable inconvenience during my travels. Although I filed a report about the issue, I have received no support or resolution. The lack of communication and empathy from their customer service has left me deeply disappointed with the airline.
