So, I recently got a job in a different city and needed to bail out of my apartment on a very fast basis (one week). I was able to arrange housing in the new city with a friend for the month, and given the popularity of the town I was moving from, I didn't think it would be very hard to fill the room. I was actually living as a subletter myself, though long-term (eight months), and things worked well enough that I never bothered to get on the lease.
I posted the room on craigslist after checking with my room-mates (both of whom were on the lease) and my landlord. Had a dozen replies in the hour, and the first girl who checked out the place took it on the spot. We worked out a moveout day, agreed to prorate the days that I was living in the apartment, and we met later that week. She showed up with her stuff, wrote me a check, I got in my car and moved to my new city.
Deposited her personal check for the amount of the month she was taking the lease up for, and the last month's rent that I wasn't going to be using. Everything went fine, until I checked my bank account a few days later and found that her check bounced. Called her up to see what was up, she said she "couldn't think of a reason why that would happen", and I told her we needed to fix it sooner than later. I told her I'd be back in town later that week to pick up some of my things, so I'd get it from her then. I did come to town that weekend (last weekend) but was never able to get ahold of her until I was on my way out of town and she claimed to be going to yoga and she'd just drop the check in the mail the next day. I gave her an address, and called her the next day to double check. She said she sent it, and we were fine.
As you might suspect, I never got anything. She claims she sent it, and my friend I"m living with says "occasionally letters don't make it to our house if you'r not on the mailbox, my girlfriend had the same problem". I talk to the girl on the phone, make it clear I need the money before the end of the month (it's been 3 weeks since she moved in at this point), and I'll be in town specifically to pick up cash or check. She says "Great, call me when you're here, I'll give you cash".
I get here yesterday and call her immediate on arriving - no answer. Leave a message, call her again two hours later, no answer. Two hours later, no answer. Now 10pm, I decide to deal with it today. Call her when I wake up at 8:30am, no answer, and drive by the place. Her car is there, I need to run an errand so I decide to wait and give her a chance to call back before just showing up at the place. On my way back, her car is gone. Call her at 10, 12, 1, and it's now 1:30. No answers.
What course of action to I have available to me? I have to work in the city tomorrow morning. I have a place to stay in town, but it's clear to me this girl may just do everything she can to not pay me my $800.
