Thank you for reaching out to the Community! I'm happy to provide some guidance with cancelling your subscription and deactivating your shop, to ensure this gets resolved.
I recommend checking out our Deactivating Your Store documentation for a complete list of steps, but will want to enter the password used to Log In to your shop when signing in. For more information, you can refer to our Logging in to Shopify document!
Please let me know if you have any other concerns.
