Seriously, Maria, with this amount of money at stake don't argue with a kid over a web forum. Get a debt collection agency involved and give them all the information you have. These people are experts at collecting money from people who don't want to pay and they will take a cut from the collected amount so it's not going to cost you anything up front.
