And right you are! (as always)
I called them on my cell phone instead of the office phone...went through the "we don't recognize this number BS" and got a helpfull live body on the line. Turns out this belongs in the check theft-fraud thread....Our Breezeline payment was one of the stolen checks and we missed getting it replaced. All good..they appreciate the $500/month we spend with them and acknowledged we're never late paying. Everything turned back on.
In '90 or '91 I had a dial-up internet account (not Prodigy/Compuserve, a real shell account on a unix system connected to the internet). I cancelled my account when I got a new job that would move me half-way across the state.
So a couple weeks later and I am setup with a new provider and I remember I had some files that I wanted to retrieve. Just for grins I tried to telnet into my old account and see if maybe they hadn't turned off my access yet. Turns out I could access it, even though they had cancelled the account. They added a file (.lockout) to my home directory that their system would check before it would let me log-in through dial-up. So I deleted the file and the account was fully active again.
Every couple of years I would log back in to see if the account still worked and it did so until they disabled their dial-up service about 10 years later.
