Contact Envato support and request removal of the comment/review.
If you contact envato support, they will remove rating like this.
It seems this rating may be in violation of Envato’s policies, so it’s likely they will remove it.
Did you check the user’s Envato profile page? It may have a contact form to reach out to the user.
Some users, after their item support expires, may leave a negative review with false claims. Then, after a short time, they might either contact you or wait for you to reach out to them in hopes of getting support without renewing. In some cases, they may be trying to pressure you for a refund by leaving a negative rating.
A while back, we suggested to Envato a feature that would allow such ratings to be flagged. During the review period, these flagged ratings would be hidden, and after Codecanyon’s review, they would either be removed or stay visible. We also suggested implementing a restriction that would prevent users with expired item support from leaving ratings, ensuring that reviews are only submitted by those with active support.
