If the reviews are actually fake, you can take action, if necessary with the help of a lawyer or business messaging feature. If they’re just negative reviews that you don’t agree with, then Google’s search engine results pages probably won’t remove them.
Read Google’s review guidelines to see if the reviews really violate Google’s guidelines. If the review is against Google’s terms and conditions and it is truly fake reviews, you should respond politely to them first.
You can report reviews to Google that you think violate Google’s guidelines and should be deleted. The relevant review will be checked and possibly removed from your listing.
