Inconsistent service reports

I have always had my car serviced by Barons in Durban until I moved to JHB where I had the car serviced at Barons Woodmead.The service reports from Barons Woodmead have been completely inconsistent which have led me to question the integrity of the work done and the service report.Last year I had my car serviced and was advised that the cam belt needs to be changed.I brought my car back the week after the service to have this done and was then advised that the clutch need to be replaced as well however I did not have this done.I was surprised since they did not pick this up on the service.This year I was given a quote for a number of things which needed to be repair/replaced & once again there was no mention of the clutch. In addition, prior to the service I had asked for a quote to repair the driver's side mirror as the device in the mirror was slightly faulty but usable. I was told that the mirror could not be repaired and had to be replaced however I did not have this done. Whilst driving home after picking the car up, I noticed that the mirror had been peeled off and was barely holding by the corner!This was not the case when I dropped my car off.Very disappointed...
