What an absolute nightmare SeatGeek has been for me. I filled out the form to exchange my tickets to Moulin Rouge weeks ago. I filled out the form with the exact seat I wanted to exchange it to. A week later, I emailed them and they said they forwarded my information to SeatGeek and "they would take care of it from there". I emailed SeatGeek. I tweeted them. I messaged them on facebook. I messaged them on Instagram. No word, nothing for a week. No acknowledgement of any kind.
Finally I called them and they said "we don't do refunds". I told them that Moulin Rouge and Jujamcyn theaters do. They told me no. They forwarded me to a supervisor. I was put on hold for 45 minutes. I was then told to call back the next day as "they resolved this conflict". An entire week later, I called them and they just gave up. "We are unable to do an exchange, we are giving you a refund.". Countless people, countless supervisors and countless hours. They could not figure it out. I hate them and I hate Jujamcyn for wanting to save a few bucks and switching to this sh*tty, incompetent company.
The short, short version? Don't even try to exchange your ticket. Ask for a refund, and then rebook.
