Why get called a cock for Xennons?
You bought a GTi for its looks and go, otherwise you would have bought a mk6 1.4 TSi, right?
Yes Xennons are way over priced, but even if they wasn't so much better for night driving than the standard setup I'd still buy them, cos they make the front end look much better.
Same story with the new rear lamps IMO.
As for the call, thats just plain stupid to think they would even consider replacing them. I've been waiting 8 months for an Edition 30 badge, so that would give you some idea of what they think at VW customer services.
