Horrible customer service. I purchased pre-ordered tickets and after I the transaction was complete I realized I had chose a day my wife and I could not attend. To make a long story short I tried contacting the company many times on Facebook and social media with no response until I threatened to contact the BBB. I did not want a refund but to change the date. I finally got a short response stating "no refunds and date and time cannot be changed". I know it was my mistake but come on man!
