Have you received an e-mail from Google about edits being made to your listing? Read our announcement on the Google Small Business Blog for more information.
Additionally: We use both manual and automated ways to ensure that new information being applied to your listing is accurate before it goes live. Clicking edit and submit in your Places account is the best way to let us know if you disagree with the edit. If you sign in and do that, after a few days, your listing will maintain or revert back to the state it's shown as in your Places account.
