How to delete TeamViewer account when you can't login

Received an email saying someone tried to reset my TeamViewer account. Problem is, I didn't know I had an account. This happened the same day my email account (Yahoo/ AT&T acct) was hacked. After the email hacking, hacking attempts were made on a few other accounts. So, I tried to sign into the TeamViewer account and change the password. My plan was to login and then delete the account, but that plan was foiled because the confirmation email never came (not in spam folder). I need to know how to delete an account I can't login to. I even created a new account using a different email address hoping to contact support. Foiled again because I have no license number. No license number = no support.
