The tickets I bought were cancelled due to covid. Box office ticket sales doesn't offer a refund but they claim to offer a voucher for any other event.
When you try to redeem the voucher, they take your number and tell you to wait for their sales team to call you back.
They never call back. When you call them again, they tell you that you missed their call.
No phone record.
Good luck.
It's a scam.
