I signed up for an online class so I could graduate, then was overwhelmed with "life" and thought I had withdrawn from the class. I did it over the computer. Then I got a bill for the tuition and told them I had withdrawn, but they had no record of it. They then added late fees and sent the amount to the department of revenue for collection. I have an email from the instructor that says I didn't participate in the class and I also filed an appeal, then the state kept my tax refund. Do I have any recourse?
