There are a range of scenarios where you can flag a bad review to get removed by Google. Select the three dots on the top right corner of the review and ‘flag as inappropriate’. There’s an option to report a policy violation- submit that, and you’re done.

However, if the review is genuine, it’s unlikely Google will remove it. The best thing to do is respond to the review, keeping it polite, professional, and listing the inaccuracies/ issues with the review.
