give a bad service and acuse the customer.

My wife took my Chev Optra in for a service and added that the aircon must be attended to as it was not getting as cold as it used to. The service advisor phoned me with a quote for the service which included a brake fluid change and an aircon service. When my wife got the car she complained that the brakes felt funny. I checked out the brakes and found that it was obvious that the brake system was not bled after the brake fluid change. This was fixed some days later but after 'n week the aircon was back to not working properly. I called them and complained again and on 4 February the car was back at the workshop. This time the technician told me, in person, that I don't know what I am talking about because the aircon is working and I must collect the car. I have been driving this car for 3 years and has always been impressed about the quality of the climate control system so I wonder what qualifies this idiot of a technician to tell me, that by keeping the car in a cool controlled environment for a day and then run the aircon for 10 minutes it is working properly. Also, why would the aircon work properly for a week after the service and then not.
