Yelp 37 positive reviews in filter, only 8 reviews showing which are mostly negative! Internet

I have a hair salon called Citrus Hair Salon. Yelp has filtered the vast majority of my positive Yelp reviews. I currently have 8 reviews visible, only 2 of which are positive. There are 39 reviews in the filter which the public will never see, and 37 of those are positive.

The filter is obviously very flawed, and it affects small businesses like mine adversly as it does not represent us fairly. This affects our bottom line greatly, as we have noticed a drop in new clients since we went from 4.5 stars to 3 stars (which is very negative in comparison to all other similiar businesses in our area). Many people look to Yelp to find out about a business they're checking out, and we are now showing as one of the lowest rated salons in Vancouver!! 

As soon as my rating started dropping, due to many of my reviews suddenly disappearing into the filter, I received calls from Yelp representatives trying to sell advertising. I was desperate to increase my rating, and so I agreed. Immediately after, my rating dropped even more. I called my Yelp account manager to cancel the advertising because I did not want to draw attention to my low rating. Of course, there is a $300 fee to cancel!

So, I'm losing business, plus I now have to pay to not draw attention to my profile on Yelp. 

Yelp should not have the power to affect our bottom line the way that they do, especially because the rating we have is unfairly skewed. With power comes responsibility.
