HELP! Customer negative 1 star review OUTSIDE THE RULES

A customer has left me a negative 1 star review where he clearly writes the price and name of another store located in the USA comparing with the price of my product that he say is very expensive in the Amazon review rules they indicate that it is not allowed to write a price and store name comparing the product that is being sold on AmazonI have made the claim to the Amazon agents and they have not given me a solution, I have reported the review directly in the "report" button and after almost a month the review continues without being deleted.
