Experts are warning about ticket scams as University of Arizona fans prepare for the Final Four game in Indianapolis, where they are trying to secure tickets for the game. Denisse Alvarez, vice president of the Better Business Bureau Southern Arizona, said that when big events like March Madness occur, the BBB sees a surge in fraud and scams. She advised fans to remain skeptical about resellers and to avoid buying from unverified sellers on social media sites like Instagram and Facebook. The University ofArizona recommends purchasing tickets through Ticketmaster, the NCAA’s verified partner for March Madness. If you get scammed, call your bank to dispute the charge and have them cancelled or freeze your card.
