Poor client service

My vehicle was booked for a service on 09/03/2023. I arrived at the dealership at around 07:10 and was number 10 in the que. My complaint is that I never received a call informing me about the progress of my vehicle during the course of the day, I had to phone the dealership myself (the receptionist or service advisors also do not have good telephone etiquette by the way) and was informed that my vehicle was next to get serviced, mind you this was already 15:45 in the afternoon. The service advisor then informed me that the driver would pick me up at 16:05 and the driver only arrived at 16:30 without informing me that the driver would be late. I only received my vehicle at around 17:35 with no apology from the service advisor and the vehicle was also not washed properly. My gripe is that there were at least 4 if not more other clients that I know came after me but they received their vehicles before mine and my vehicle was also not in for a major service, I wonder why is that? I definitely have a suspicion that there is favoritism at play at that dealership especially when it comes to the managers. All round the service and attitude of the staff are just bad and I would not recommend this dealership unless you have not other choice like I had. I just hope my vehicle was serviced correctly since they most probably did a rushed job so I will keep an eye out for that.
