Last summer (2011) I was in a bit of a pickle. I had recently moved into a new place where rent was low, but the power needed to get changed into my name. I had a bill from a previous place that I'd been trying to dispute, but they wouldn't turn on the power unless I totally capitulated and gave up on ever contesting the supposed debt I owed to PSNH. So I had to accept defeat on that point, but figured I could pay it off over time.
No such luck. They demanded a payment of over $500 just to keep the power on. In fact, they were sending someone out to cut off the power when I was finally able to get enough loans to keep it on. Thankfully, I was able to talk them into waiting until the next day, which enabled me to beg and borrow enough to cover that. This debt is part of that.
Update: Finally started paying this one off.
