Frontier Airlines EarlyReturns - 24 Hour cancellation policy

Does Frontier offer a full refund on flights purchased with 24 hours (like United)?

I know i had a brain cramp and booked for the wrong week, instantly realized it when I printed it, and called back. Issued a credit and I rebooked. Not sure if that's official or not, but it worked.

Frontier is very good about correcting any mistakes you make on the web, provided you call them with 24 hours.
Make sure you've communicated well. By "credit" does that mean you will use the credit for a future trip, or your credit card will be credited so you won't be paying for two tickets? Better clarify that.

Last time I tried, they said they do not allow for 24hrs grace period.

any updates to this?
thanks,
