basically, provider with long history of awesome reviews. i personally saw her last month and vouch for her. the reviewer is newbie. review has many inconsistencies. What can the provider do about it? (i tried to search for a discussion of this topic but i didn't know the right keywords.)

where is says "contact us" and state why she feels the review is bogus.

In many cases, they will take down a review they feel is suspect.

Good luck to her.

This review is clearly unfair.  He describes BBBJ, kissing with tongue, daty, a finger in her ass, and multi-position sex.  He then awards her only a 5 for performance?!?  

Advise her to report a problem on this review, and report a problem yourself!!!  

Unfortunately, there are some guys who are never satisfied, and the gal suffers.
