what to do if a provider brags to you about a client that did not work you but work for her.

there is a provider in my town,I one time client that I had problems with a client ,I told her I thought she thought she was better then me for getting a client of mine when she did not care about the problems I had with him,He was an hour late show up with calling or emailed and he did not answer nothing from me so I got comfortable got in jeans and shirt turn up the music blow out the candles and was blaming me cause his lovestick did not work ? I told her since she do not care about what happen and she said I wanted was to know if he was legit. By Sending the review about the client in question she sends the review he had written about her.Since she sent the review Does that prove she did thought she was better from the start yes or no?
