If they were even smart, they'd put out a letter like this with a small amount, say $300 - there are a lot of people out there that would probably pay it in a heartbeat rather than lose their house.
Even if I am in no danger of losing the house, I'm going to bring this to a lot of people's attention. It's just downright nasty what they are doing.
Good!
I hope you kick their asses all the way to Tallahassee!
We're pulling for you.
