I would like to know if it is possible to turn off the function in which people can leave reviews, or if not, how to remove unfair reviews.
My chief concern is a review that was left yesterday. It was a blatant lie and was not written by a customer, but instead a person seeking some sort of retaliation.
My small business is run by a dedicated, hardworking staff who deserve to excel and have a great livelihood. Unfair, harassing reviews threaten this, and I need to know how to fix this problem.
Nope you can't turm off the reviewing feature for your lsiting.
your best choice is responding as owner on such bad reviews:
