Received an acceptance this AM but unable to cancel MCAT retake tomorrow?

Hello everyone! Applied to the 2019-2020 cycle with a 503. Received interviews but no acceptances through the spring and decided to apply again after an MCAT retake- scheduled for tomorrow. Today my top choice offered me an acceptance to this year's class, starting in about a week, based on last year's application and score. There's no reason for me to retake the MCAT now but the last official day I could cancel was 07/15. I called AAMC and have been on hold for 20 minutes. Thought maybe... Received an acceptance this AM but unable to cancel MCAT retake tomorrow?
