I bought tickets to the Formula One races in Mexico City on October 17th 2025. The race is in one week. After my payment was processed, they sent me a whatsapp messages, saying that the charge I paid didn't include taxes (This despite the handling fee being ridiculously high), and that I had to pay their tax or they wouldn't send me a ticket. They also said, I couldn't back out of the transaction because my payment had already been processed. Good thing I used American Express to purchase the tickets.
