I purchased tickets online I was overcharged for 2 tickets totaling $90. It s been 3 weeks and still no refund when you call and ask they re extremely rude and will not let you speak to the people who do refunds. They told me 12 business it s been that and still nothing be very careful ordering online from them they can take your money instantly but takes forever to get it back. Not even an apology for the mistake.
