Let me pose a question
You self diagnosed it as a simple fuse...which was correct, great.
Your expectation was that they drop tools and get onto your car asap.
Lets say it was more time was involved than a fuse...diagnosis time needed, scan the
ECU, test nav unit etc
What happens to the pre booked cars? Those jobs aren't as important?
What happens to the cars with customers waiting in the service lounge? They wait longer so your car gets looked at.
It is all about expectation management.
Was it a Vehicle Off Road (VOR) situation critical?
Blow ins are part of the deal for service departments but the customer needs to have reasonable expectations in my opinion.
But no, the customer is always right.
''this is just the icing on the cake from this new mob......my wife has purchased 2 new vehicles with a lot of accessories and had these vehicles regularly serviced at this dealership''
The other customers that you wanted pushed aside so your car could get looked at, obviously aren't as important
The fact that you even posted this makes me shake my head.
