TICKETMASTER purchases tickets at times from 3rd party vendors. It is impossible to get a refund if a venue has been POSTPONED...Even tho the performers are not available at the time of your purchase and venue date, they indicate "postponed" and refuse to refund your money as it is not a CANCELLED event. Also, no where on your ticket does it indicate any vendor except Ticketmaster and the 3rd party vendors will screw indicating "postponed" instead of cancelled so you can't get your money back. Never again!
Be very aware!
