Snoops:
Admittedly you have had shocking service from your particular VW garages. Yes, you have every right to expect a high standard of service especially when they can see you are a careful and discerning gentleman owner. Their overall behaviour towards you has been shameful.
I have had superb service from my VW Service Department. My issues were with the Bodyshop which is now part of the FixAuto Franchise which both VW and Audi use. Then there was also the crass behaviour of VW Technical, though VWCS were supportive as was my excellent Warranty Manager.
I have had no issues with VW anymore, especially since I wrote a strongly worded letter to Chris Craft, VW MD. In fact, the standard of service I have received has reached dizzy heights. Most impressed.
