Catch 22.... Can't access email, therefore can't cancel subscription or use applications

I previously had an educational Creative Cloud subscription using my university email. I graduated recently, so my educational email was deactivated. 

Now whenever I try to log in to my Adobe account, it sends a verification code to that email. The email is deactivated, so I am unable to receive the OTP verification. There is no option to receive a code via text. This means I am cannot use any of the applications I am paying for. 

I just spent half a day on the phone with Adobe customer support trying to change the email associated with the account. This is not possible without having access to the current email and providing a OTP. I am also unable to cancel the monthly subscription without access to the account. 

So…. it feels like I’m being held hostage, I can’t use the services I’m paying for and I’m not allowed to stop paying for it. My next step is to contact my bank and cancel the direct debit. I have just had to start a new plan because I need to use Photoshop today, so I’m currently paying for 2 plans at the same time. 

Has anyone found a way around this? Customer support was not much help

Thanks everyone !
