"With fees and costs, the four RATM tickets cost Plaintiff approximately $590. On or around March 15, Ticketmaster informed Plaintiff that, due to the coronavirus outbreak, both RATM concerts would be indefinitely 'postponed.' Ticketmaster, however, would not refund the total amount Plaintiff paid for the RATM concert tickets. Plaintiff now holds four tickets to two RATM concerts that have been effectively cancelled, will almost certainly be cancelled, and which he bought with a guarantee of a monetary refund for cancellation. But under Defendants' new, post-hoc policy revisions, he will only be provided a refund if, and when, the events are officially cancelled rather than 'postponed.'"
