How do I cancel my Diamond subscription?

Do you have access not the email? If so, use forgot password.
I used log in with Google so I am unable to do that. Yes, I also forgot the email. My card is still linked to the account and will be charged soon.

I was paying for a Diamond subscription on an account I made, and then I accidentally deleted all cache and cookies, and now I lost my account but remember the username while my card is still attached to the account. And support seems like it is taking a godawful amount of time.
Contact support directly using the option in the menu. Be sure to choose the billing/refund related option.
Support should be able to validate your identity based on payment method
