Well, if they have not sent you the statutorily required claim to the deposit, you can demand it 30 days after vacating it.
You should look to the terms of your lease agreement (the one you signed) to address the remainder of the issues here. Hopefully you took a lot of pictures before you vacated.
You may need to consult with an attorney, which in your situation can be difficult. I recommend that you contact your local legal aid for assistance. They will try and sit you down with a landlord tenant attorney to go over your case with you.
