Report the Review to Google
Google will remove reviews that violate Google’s content policies. Spam and fake content are clearly prohibited content. Other prohibited and restricted content includes off-topic, profane, sexually explicit, threatening, and/or discriminatory content. If the review-in-question includes any of these, then you can report the review to Google. Click on the little flag icon next to the review and fill out the form to report the policy violation.
It will take Google a few days or even up to a week to review your report and make its decision. If successful, the review will be removed or put on hold. If the request is rejected, then you can consider the legal route by contacting an attorney.
