The Phantom of the opera performance I have tickets to has been cancelled..how can I redeem for for a performance not cancelled

Yes give oakdale a call if purchased through them. They will either give you new tickets to another performance or refund. If purchased through stub hub they will just give you a refund on credit card once they are informed it was cancelled. No harm in giving a call.

Who did you purchase through? If directly from the theater give them a call...I'm sure they will allow you to see another performance

Kyra gave a good answer. Best wishes with recouping the value of your tickets. If the history of the event cancelled the show... You should be due for a credit unless it was on other terms.
