If there is such thing as a digital mafia, this company is it! Some of the same buzzwords can be used to describe them.
They "hide" great reviews and display $#*!ty ones, then give you a call and try to get money out of you at which point, your good reviews will magically show up and affect your overall rating.
I'm sorry, but if any other company did this... "pay us money and be honest" scheme, they would be burned at the stake.
Yelp, I've got a 1 word review for you - $#*!.
