weird situation

Hello,

Last month, I attempted to sign up for Adobe Acrobat's free trial. Unfortunately, I inadvertently mistyped my email address, entering "gmial" instead of "gmail." Despite this error, I was able to add my payment method and initiate the free trial. Later, when I recognized the mistake, I tried logging back in to correct it, but kept receiving an "incorrect email" message. To make matters worse, I was charged $30 last week, and I'm unable to access my account to cancel the subscription. I'm unsure of how to proceed now, it would keep charging, and I am not able to log in to make the correction or even use the services.
