Flag and fix inappropriate reviews
Reviews that violate the Google review policies can be removed from Google My Business listings. See the instructions below to either flag an inappropriate review that you find on your listing or fix a review you wrote that's been flagged or removed.
Flag a review
If you find a review that you believe violates Google review policies, you can flag it for removal. The review will be assessed and possibly removed from your listing.
Before you begin
•Check the policy. Only flag reviews that violate Google policies. Don't flag reviews that you don't like but are still factually accurate. Google doesn't get involved when merchants and customers disagree about facts, since there's no reliable way to discern who's right about a particular customer experience. Read the policy before flagging a review.
•Be patient. It can take several days for a review to be assessed, so don’t contact support right after you flag it.
