@isagalaev I once subscribed to #matchroom to see a tourney and they removed it from the service after the first 2 or 3 days. They also refused to refund because it was a monthly subscription (I did end up watching 1 other thing later, but I wouldn't have subscribed just for that)

Maybe your case was similar, in some regions the event goes to DAZN and matchroom can't show it anymore, people need to check event by event (and, as it happened to me, event after it starts, it's not 100% guaranteed)
