Very Bad

I had a 150km service done by Bosch Service station the Reef and when i got my vehicle back Plug wires 1 an 4 loose. not to mention of brake fluid that was not even checked. The Engine was sill dirty. How do you put spark plugs in with dust on the sides still there Also a Cable tie on filter box that wasn't there before. They also took a test run after service and not before. The car had more power before the service. I would not recommend anybody to go to bosch service the reef ever.
