Easy to see what happened, it's written on the wall.
Lady rented for 1 year, deposit 32,000bht
Year ends, Lady waits for return of deposit, "I'm not leaving until I get my money back"
2 weeks later no returned deposit, so trashes the apartment.
There is no legal way to get your money back.
Court action will take at least 2 years, and most tourists can't sit in Thailand doing nothing for that long.
