Do you have a G Suite account, a Google Cloud Platform account? What type of account do you write about?
Have you upgraded your G Suite account from Basic to Business and now you want to revert to Basic? In the latter case, you may follow instructions published on the "G Suite Administrator Help - Downgrade back to the legacy free edition"
page. You can’t downgrade back to the legacy free edition if:
* Your free trial expires.
* You set up billing and add more than 10 users during your trial.
* You never upgraded from the free edition.
* You cancel your subscription entirely.
