Bought tickets to Rage Against the Machine at MSG in 2020. The concert has been rescheduled twice due to CoVid. Each time I received a notice that tickets will be honored for when the concert is reacheduled. However, when I go to my account it does not show any tickets. When I search the access code/order number, I find E Tickets for the 2021 rescheduled date. How can I be sure I have tickets for the current event?
