Reading between the lines...'the car should go to the factory for servicing apparently' .....a sad indictment of some of the service levels within the dealer network.
I would be pretty pissed off under the circumstances and I would be wondering is this a one off and now a permanent fix or could it happen again. None of it would fill me with confidence especially on such a critical component.
