You are having the same luck as I had with my Tiggy 1.5 TSI elegance Moostone grey Storm interior ordered and Mar. After months of waiting for a delivery date I checked on the VW order tracker and the car had been changed to a Dark Grey metalic with black cloth without my or the dealers knowledge!!!
I had to get in touch with my dealer to tell them I didn’t want dark grey paint and as delivery was still way in the future (week 36) I told them what colour I would accept. They came back and said we can’t change the colour even though build week had slipped back even further to week 38 (and that was provisional) so I told them as they could not deliver an acceptable colour to cancel the order.
What a shower!!!!!
