Burn it down

Oh the joy of looking for a place to live.
I recently found the perfect townhouse. It had everything we needed. We got everything in order, the unit was paid for and on reserve for us, but about two weeks before we were supposed to move we got a phone call. My landlord-to-be called and said "Im sorry but I dont have a unit for you to move into." She was asked why and told us that even though she was paid for the unit and was supposed to reserve it for us she just didn't do it and rented it to someone else. She just completely forgot about us after taking the money. She ended her explanation with "Im really sorry, I have never had that happen before but there is nothing I can do." I have never been so mad in my life. I just think that if you are to scatterbrained to run and maintain rental properies you probably should not run and maintain rental properties. At the time I just wanted to smack her, and now that I really think about it, I still do. Now it's one week before we were supposed to move out of where we are and into the new place and we are back at square one looking for somewhere to live...
