Welcome to my daily life living in Colombia where every web page has some kind of problem either with my address or my credit/debit card(s). Nobody can tell me if it was the local credit card processing company's problem or my bank that rejected a charge. I say nobody, because customer support doesn't exist here, as it doesn't in most USA companies anymore (after 48 years being a Bank of America customer, I just closed all my accounts with them). A $4,000 cruise reservation I made just lapsed because I couldn't chat with anyone about a problem in the small print that indicated I wouldn't be getting what I paid for based on their deceptive advertising BS.

And it's not like that venue is sending you a package that you shouldn't receive. They know exactly where you'll be that day and time.
