How to know if my purchase of tickets for the July 11, 2019 concert was successful? A notice came out that had exceeded the time but I had already put the data of my credit card ....

Hours open today

If they did not send confirmation, I think the purchase was not

Email the box office they are very fast to respond. I suspect that the time out over rides your details being entered if not completed.

Maybe I could check your email to see if you have a verification of the purchase of the ticket?
