@Frances7, this forum is not administered by AirBnB. It's simply a place where hosts share expriences and offer advice.
In any case, a review can not be deleted unless there are extremely extenuating circumstances. In that case, you would need to contact AirBnB directly. A contact link is included in the thread entitled 'Community Help Guides' near the top of the front page in this General Hosting section.
I see no negative review on your listing. Are you referring to a review that you gave to a guest?
