You can’t hold money for a postponed show that may not even happen at this rate.
We won’t know if the company (or any company, for that matter) will be operational in 2021.
Actually most ticket outlets give that exact verbage when you click buy. I agree they should offer refunds though, but it may be out of MKW's control. Its no different when your favorite band postpones for a year and you don't get a refund from ticketmaster.
MLW has a big money backer and just signed some new overseas TV deals. Money isn't an issue unless that all goes away.
When I got my refund when they rescheduled it from April to June and MLW or Court Bauer wouldn't respond to my tweets, I eventually just went through Eventbrite. There was an option on the site. I was refunded within a half hour.
