Maybe your accounting system was changed or you've created an account without intending to. If this is the case, you can easily cancel your account.
This is how you cancel your account
Click on your avatar and open Billing & Subscriptions:
Go to the Account Details tab, then click on the Three-dot icon and select "Cancel my account":
In the pop-up, click on YES to confirm your account cancellation:
If you have any active Organisations, you need to retire or transfer them before cancelling your account; otherwise, you'll see an error message:
Once confirmed, your account will be cancelled. You can always create a new account by clicking on CREATE ACCOUNT:
Then select your country from the drop-down list and click on Confirm:
Please note: If you cancel your account, all Organisations under the cancelled account will be deleted automatically and you'll lose access to their history, even if you create a new account.
