Damage lagguage Bags

I flew From Cape Town to Johannesburg on the 29 September 2021. My bags we damaged badly. On the very same day I called the Airline and I was told I need to send an email with pics and my boarding pass. I did all of that only to be answered 7 days later after I went on their Facebook inbox. I received a response from Ellerser Malagas Stating that it's not their responsibility but of the airport which are handling the regulations. So I again I cced The Customer care service at the Airport and their response was I must address this with the Airline. So basically I'm being tossed around without any one explaining how my bags were damaged like this This is really radiculos!!
