How to Contact Google to Cancel an Account That Has Been Compromised

If possible, secure your Google account before sending in an account cancellation request. Since your Google account may be associated with services such as Gmail, Google Docs and Google Checkout, taking action now may prevent harmful consequences. If you are unable to access the account, notify Google immediately so they can help you recover the account. You will not be able to cancel the account until you are able to log in again. Expect a response from Google within 24 hours.
