I would probably do the same in your shoes. I'm in a place by myself so naked was the choice for me, and ended up Snap.
Telecom didn't offer it when I signed up over a year ago, shame they still don't. But I've been happy with Snap, I have Telecom 3G handy just incase, but the odd short problem was fixed pretty quick smart. All in all, I don't actually remember any problem if I had them, so they were nothing worth remembering. Only one, and that was my router's fault, and Snap knew the bug and had me on the right track in minutes.
Thing is, when I was looking at prices, Telecom's lowest costing broadband package was only $75. Five dollars more than the SNAP package. But it only gave me 30GB and I didn't need a landline. I found it odd because I know Telecom has been upping the data for people on existing plans, why they haven't upped the data on that plan, not too sure. If it was 50GB it would have been a value add having that phone... but as it currently stands, I'd be paying for something I didn't use, and not getting enough of what I do use. :(
ANYWAY, GL to the Telecom crew. I'm sure they're doing everything they can. :)
