Pathetically Poor Service!

We bought a second-hand Amarok and the vehicle was paid cash and in full. When I had to go and collect I found that the vehicle wa in the workshop with some or other gearbox issue. They made me wait there from 08:30 to loooong after 13:00. I now have to sleepover in a guesthouse and that was not part of the deal. Who is paying for that?
