Car service

I went to Car Service City Celtisridge, Afrikaans guy called Cornelius or however it's spelt, confirmed booking on 2023.12.14, I requested pdf and he kept saying they cannot get. I get there to take in car for service he says to me they have to check it in and he calls the insurance and sends the pdf to them. I then say fine check in the car, he then says no he will kot check it in as I hang up the phone. I ask him when and what time, he did not answer and says he doesn't want to argue. No call nothing.
