Service Department

I booked for my car service on the 01/04/2016 morning, later they the person by the name Lebo called me notifying me that they damaged some parts in the engine that needs to be replaced and they have ordered that particular part, I asked Lebo to put me through her immediate manager by the name Rodrick but unfortunately he couldn't call me back to explain. I needed to use the car to go to the funeral down in Limpopo [Polokwane], I had to hire a car at first car in Rustenburg for three days of which costs R495.00/per day plus deposit of about R3000.00. They promised that my car will be ready on Monday 04/04/2016, comes Monday the very same lady called Lebo called she then informed me again that their still waiting for the part to be delivered and that add another day to Tuesday 05/04/2016. My frustration is if they knew or understood my predicament they were supposed to loan me a car of which they fail to do so. What I need from them is to compensate my costs to hire car and all the fustrations. My car registration is YWT 710 GP. Please intervene.
