CANCEL SUBSCRIPTION ATTACHED TO NON-EXISTENT EMAIL

Hello all!

Trying to figure out how to cancel a 7-day trial subscription before next week Tuesday. I accidentally typed in a shortened version of my work email when setting up the account/entering card info so the email that the credit card information is attched to essentially doesn't exist. Any help would be appreciated as I would hate to charge my boss 100 dollars as the intern 😞 Thanks! For reference, I have a legitimate email with the company attached to an additional account, however, this email has no manageable plans attached to it, however, Im hesitant to add the seven day trial to this email without cancelling the incorrect email.
