Thank you. This is very interesting.
I understand that it was at first quarter end but nonetheless it sounds like a risky approach; they could have accepted your rejection.
At the end of the current quarter there will, l hope, be some cars for collection but, with so many orders backed up, they might feel quite confidant in accepting a rejection and passing the car to a "wait list". Or, is it possible that they could reject the complaint but still give the customer an opportunity to withdraw the rejection and accept the car "as is"?
You seem to be quite knowledgable on the way these things work. However, I can imagine that company policy, if not capricious, is quite dynamic.
It would be nice if these genuine complaints could be addressed with fuss.
