Please what does Airbnb review policy say about guest booked unbehalf of someone?

[Kaydee2]

Some customer support acts based on their personal opinion and they seem to come up with their own conclusion, which is frustrating to host who put in everything to sustain their business.

A guest who neither visited our place nor stay in our listing left us a review.
This guest wrote a review like someone that stayed and experienced our service firsthand and Airbnb customer disregard their review policy despite showing them where it is clearly written that a guest can't leave a review on a listing if they didn't stay there in person.

The customer support have really frustrated me on this, despite sharing a link to their review policy and also show where it is clearly stated.

What can i do? 

Please help me.
