Worst Business Etiquette

On the 14th April 2021 I took my vehicle in for what assumed was a small pothole issue, which then turned out to be more than expected. (Cracked axel, Shock, wheel, etc) I was assigned a gentleman by the name Isaac, who never gets back to messages left for him. (They just do not respond on ETAs, or just mere curtesy calls). I received a text that my car was ready on the 1st June (Month and a half). On collection 2nd June, I found that they had dented the bonnet. What I don't understand is why take the initial pics and not inspect the car before the client. I asked to speak to the manager as I had other questions regarding the repairs (Front Bumper resprayed, why?. Is it normal for your consultant to not follow up on calls and/or update clients). 40minutes, later he still hadn't come to speak to me. I subsequently left the establishment, and till today(8/06/2021) I still haven't received a call from them. Got a call from their head office, expressed my disgruntlement, but still no answers. This is the worst business etiquette I've ever seen. I will never use them again. I expect to receive my car fully repaired, all missing seals there and no fillers on that bonnet (If you can't fix the hood, replace it).
