I had a slit at 11:30 for a free Air conditioning check. They took the car inside the working place at 13:15. Kept it for 45 minutes without working at all. Just had the bonnet open. But I could see everything. Finally someone drove the car out. He handled the keys and told me that there was electrical fault on it. In other words the mechanic never vacuumed the air cond system to see if it sustains vacuum or not. Neither tried to run nitrogen to see if there was any leak. Bottom line, they just got me back because I left them a bad review a few weeks ago on MOT of the same vehicle, and it showed on their records about the previous experience with the car serviced by them. By the way. In their system it shows that the todays work never took placed as it was cancelled by me. So now you know all about their ethics too.
