Hello! I am having trouble purchasing tickets for the Oskar Schindler Factory in Krakow. I have tried two different credit cards, a debit card, and Google Pay. Each time I put in the payment information, I get a transaction failed message, but the charges have shown up as pending in the credit card account, only to later disappear later. I have received ticket confirmation emails and a few hours later, cancellation emails.
I think I read that tickets should be purchased in advance. Does anyone have any suggestions or tips?
Thank you!
