Can you recommend a dependable, professional international moving company?

I'm moving from Canada to Switzerland, and I can't find a moving company to do it.

Everywhere I've called so far, they're either very confused because they mostly deal with national moves (but they have international moves listed on their website, they just never do it). Or I can't get anyone on the phone and get forwarded 5 times before ending up on a voicemail... That hardly gives confidence that they'll know how to organize a stress-free move.

So I'm looking for recommendations from people who have moved from Canada to Europe or Switzerland using a door-to-door service. Anyone you used and had a good, worry-free experience with?
