I bought tickets without a membership. How would I go about cancelling my ticket and getting a refund? I tried calling the help desk, but they couldn't answer and their inbox was full.

That is how I went about getting a refund before, I called the theater

You need to go in stores and ask for a refund or go online and ask them personally

Sorry, there doesn't seem to be another way to do it according to the website

You should go in person
