Very poor client service

I. took my car for service in barloworld toyota centurion on the 11 jan 2019, since in the morning they only called around 13:00 to inform me that they are starting with my car, 15:30 I called them to find out howfar are they so they said they are taking it to be cleaned because they have finished with the service. So later on I went to collect it because they said they will be done I n the next 45min. Unfortunately they were still busy cleaning it, only to find that they are still servicing it, it was around 4:40, so I went to ask the service manager, what is happening because I got the impression that my car is finished with the service and that they are cleaning it, but he ignored me. Now the service advisor by the name of ***nor Rank was responsible for the service of my car and she is the one who is behind all this. Now I paid a full amount of R4000 for nothing because my car has not been serviced as they claim it was. There are no sample to show that they have replaeced any parts and the parts in the car are still old. They didn't even check which part of the car needs to be replaced they didn't even call me to ask if they ca/ replace anything, I.e window wipers are worn out.
