Car service

I'm the owner of Ford ecosport 2016 model wirh leather seats and it was brand new when I bought it. On the 22 March 2024 I took my car for service to action Ford Roodepoort. On return I noticed that my car was torn or seems to be a cut on the side of the drivers seat which wasn't there when the car was taken for service on the 22 March 2024. I contacted the branch the last who assisted me with the service and I never got any feedback from her instead I got an email from Roodepoort manager who informed me that this was due to disforming of the leather seat due to seating and it was not done by any of their service team (conclusion made based on pictures sent via WhatsApp). Thereafter the manager does not respond to my emails until the service lady responded that I must contact their customer care of which I did. They informed me that thy take what the branch is telling them and there's nothing they can do. They further asked me to produce the proof that the car set was not torn when I brought it in of which I didn't have. When I also asked for proof that the car seat was torn when I brought it in since they assessed it, they also did not have it. I kindly need your assistance. Firstly my car wasn't torn when it was taken in. Secondly the leather seat can't just disform overnight. Thirdly poor communication from the branch. Lastly my car set got damaged when my car was in their possession. I've contacted so many Ford departments eg Ford SA, Ford complaints (email available online), no one got back to me. All I need is for them to take responsibility of my car getting damaged whilst it was on their possession.
