Not that anyone on this forum would consider such an ISP, but just a note in case they've forgotten:
This is the worse provider in the world. It's a company of such incompetence that they couldn't make a sitcom about it. They have everything, from lousy service, to incorrect billing, to a complaint department that's rude and unresponsive. If it were a hotel, it would make Faulty Towers the best hotel in the world.
Avoid at all cost (buy a carrier pigeon)
