So, I've been trying to register a new slam through the https://www.poetryslam.com/poetry-slam/new
page, and every time I do I get an error message of some kind of error page. Usually it's the "ERROR 500 - INTERNAL SERVER ERROR" page, though occasionally it will just pop up with a single line of text about an invalid time-out or something like that. I've tried this about 4 times so far, and I'm a bit worried to keep trying in case the site decides to charge my card every time I submit the form.
Is there a way to check and see if the page has charged my card already, and the info went through? I'm assuming it didn't, since I didn't get a confirmation e-mail, but again, I'd rather not suddenly see 4 charges for registration on my card... is there a way I could do this over the phone?
The registration, by the way, was under the name "Fayetteville Word Wars".
