I accidentally purchased tickets for a city 8 hours away. While waiting for customer service, I kept being jumped around in the waiting queue. I would be #4 then pushed to #5... then #4 again and pushed to #5. Then I made it to #1 and was pushed to #2... then #1 and pushed to #2 again.
Finally, when I talked to someone, they couldn't even give credit so I could buy the ticket for the correct theater.
I have learned my lesson. If I want to ensure we have tickets for a movie, we will just go to the theater extra early or not see the movie at all.
