Just do it yourself, you're not going to damage the trim if you're careful, use a cloth around a knife or something to get it off. What if VW damage it? They're probably less likely to care than you are. If they're doing it as a favour, I doubt you could get them to replace anything they damage either.
If I was at home I would screenshot Elsa which shows where the clips are located for the trim. It's fairly straightforward though. I wouldn't be afraid of pulling it. I don't think it's exactly expensive to replace if you break any clips, it's the dash you've gotta watch you don't damage.
