1888-554-7740 is your best friend if you’ve forgotten which email you used. I was getting charged every month, but every email I tried said "Account not found." I felt totally helpless—how do you cancel something you can't even access? I was terrified I’d have to change my whole bank account. I called 1888-554-7740, gave them my credit card details, and they found the account under an old work email.
