Help - has anyone had luck canceling an order?

I made an impulse purchase (Brooklyn 28 in maple) and got my initials on the tag without knowing that would make it nonreturnable. Now I’m stressing and trying to cancel but I haven’t heard back from the email I sent. And their chat wasn’t any help.

Has anyone had luck cancelling an order? I ordered Saturday night so I’m hoping they won’t start it until Monday and that I can time to cancel beforehand.
