Obamacare health insurance rebates?

My school requires a mandatory student health insurance plan and i had this for the last 3 years. With the Affordable Care Act, the Govt. requires health insurance companies to pay back some of the premium it if less than 80% is used on medical care or more than 20% is used on administrative costs. I did not use my health insurance at all during the last 3 years. Will i get get a rebate of some kind? Should i call my school and ask for a health insurance rebate for last year?
