I'm just a consumer, i can't answer the question definitively. My VDSL's with Snap, haven't needed to call them at all except when i was setting the router up for the first time. They have a couple APIs and respected my right to disable the "support account" (backdoor) in the supplied AVM router, which was cool. The internet at 'the office is a zero-rated relationship with a datacenter my parent company partners with, so i can't comment on that. I don't know if this is the place for specific recommendations, you might find more opinions on say geekzone.co.nz.
