I purchased ticket in Feb 2020 for a show on May 1st. It was rescheduled for August, then rescheduled for November, then to be determined. The tickets I received were through Ticketmaster. The event has been cancelled. Ticketmaster has refunded Box Office and they refuse to give me a refund. They have offered a voucher for a different show. I am not interested in another show and have since developed medical issues that prevent me from traveling to Oklahoma. Don't purchase tickets from Box Office. refund.
