Eclipse are a joke ISP now, especially compared to what they were a few years ago. I swapped from Eclipse to Zen back then due to repeated technical support failures and have never looked back.
A friend of mine is currently trying to escape Eclipse's clutches. He thought he'd finally cleared up the terms of leaving when they quite clearly reassured him on the phone that his account was closed and that his ballance was zero a month ago, then a month later he's getting threatning letters saying he owes a months subs and that they 'will take further steps' if he doesn't pay right away....
It's clear that the one hand doesn't know what the other hand is doing at Eclipse because the letter doesn't say he owes just like a final month or whatever, it asks him to set up a direct debit!! For a service he terminated a month ago LOL..
Awful service, patronising and awful customer services, and billing. You are better off away from them in my opinion, but be prepared for a few months of harrasment even after you finally think you've left them
