COBRA Policy Cancellation and Prorated?

If I cancel my insurance midway through the month, will I get a refund of the amount of money not used in the month?

Premium payments for your COBRA health insurance continuation coverage, will coverage for a full month. Major medical plans will most often start on the first of the month and end on the last day. Generally, there are no refunds when you cancel your plan early. You may contact your administrator or your past employer for specific insurance payment information.
