Terrible workmanship at Bosch Tokai

Fiance had our car serviced there three days ago. Shortly after, the car started shaking upon switching it off. We went back today and received utterly disgusting service from Faizel, the manager at the Tokai branch. Faizel nonchalantly asked my fiance "is this your problem" and then revved the car multiple times and drove it into the service centre with the bonnet up! He also handed the keys over and when my fiance got into the car, he had left the car in reverse with the handbrake down. The car was rolling back and forth.

I'll be having the car looked at another accredited auto services provider to ensure that the service was actually up to standard. It is disappointing that I have to spend money twice because the first time around the couldn't be bothered to provide adequate services.

I would like to know if this is the normal service standard at Bosch Tokai.
