Wow, that's some really interesting definition of 'fair'
If you or me don't pay our bills, I fully expect the service to be terminated in 30 days... probably less than that in fact.
Shitter shouldn't get the same treatment as a big, well-known client (although given the quality of Google's support, I wouldn't be surprised if they do, thanks to runaway automation that can't be tamed even for big clients they very much want to give leeway to)
Shitter is in fact banking on that as part of renegotiations.
I find it completely fair if they did get the same treatment as everyone else.
They will cut you off when the time comes, but it can sometimes be surprisingly long. And they will put a lien against the property, too.
In my case it was their fault. I configured automatic payments and they migrated their online system and subsequently dropped my data for payments. Still, they were ruthless about it.
What I've usually seen is they threaten to shut you off with very strong wording, and then continue to threaten you for 3-6 months before they bother to send someone out.
This was a common occurrence that people referred to as 'brown billing' because the shutoff notice had a brown header instead of the green header on your regular utility bill.
