How do I report a dishonest tradesman

I got a quote from Sunny clean. They asked for a 25 percent deposit. When I tried to pay it, my bank told me that the name sunny clean was not associated with the account details they gave me. When I asked them about this, I looked up their reviews, they were terrible. One of the few good reviews was written by Galin Ivanof, who in fact works for the company. I used your website to try and avoid people like this.
