Poor service and damage to prooerty

I took my car in for service at Auto Alpina springs on 21/12/2021 at 08h00. They called me around 14h00 Grace called to tell the vehicle was completed and the driver will pick me up. An hour later I took a bolt from Nigel to springs to go collect my car. I a realized my TYRE had a bubble and rim was damaged. I went back to complain and service manager said "I can't believe it happened here". A guy who did the checklist on the vehicle was called and the bubble on the Tyre and damage on rim was not mentioned on the checklist but he confirmed verbally with a shaky voice that it was there. Then after I was attacked by the entire center staff verbally as I came to steal. I sent a complain through their website and Servino replied also denying accountability of the damage on my car. I feel very bad with the service I got and being ill treated.
