I've said screw amertitech. I contacted their executive offices, and they refused to recognise my faithful payment history. Fuck them. They now lose twice. Once because they could have won back my POTS line, and then sold me DSL. Screw it, they get neither. I hope they're happy. I found a new ISDN provder that sells dedicated 128k ISDN for $50 a month, I'm happy now.
