While purchasing tickets for Cabaret on Broadway, I accidentally purchased tics for the wrong date (had 2 windows open!). I immediately realized my mistake, found a customer service phone number and called. I explained what happened to 'Kate', and was told that it may be possible to exchange tickets for the date I actually wanted. About 4 hours later I received a call back with a confirmation that the exchange had gone through and that my new tics were available on the app. I know that SeatGeek policy is that all purchases are final, but because these tics were a few months out they were able to assist. I appreciated the customer service.
