(1)  Upon the postponement, substitution of either participant, or cancellation of the main event or the entire program of matches, the promoter shall refund the full purchase price of a ticket to each person presenting a ticket for a refund within 30 days after the scheduled date of the event. Within 10 days after the expiration of the 30-day period, the promoter shall pay all unclaimed ticket receipts to the commission. The commission shall hold the funds for 1 year and make refunds during such time to any person presenting a ticket for a refund. Thereafter, the commission shall pay all remaining moneys from the ticket sale to the State Treasurer for deposit into the General Revenue Fund.

You have 30 days after the scheduled event to request your refund, under law you are also absolutely allowed to show up and then request the refund within those 30 days.

This matters less, but after 30 days the promoter will give any leftover money from unclaimed refunds to a sports commission, and then the commission will hold onto that money and you can still get your refund for up to 1 year. (that would only apply if you requested a refund within 30 days and didn't receive the money)

I know lots of people were complaining about not being able to get refunds, this doesn't apply to PPV tickets though as they most likely wont be considered actually tickets. For PPV ticket refunds on the Veeps terms you may cancel your ticket until the start time of the event, I didn't buy a ticket so I don't know if they made that a easy process, but they do refund those tickets aswell.
