Action Repair, Inc

This guy is a scammer and my lawyer is preparing to take him to court soon . Last month he came to fix an oven at my restaurant. The problem with oven is blowing up every time you try to turn it on. Something with pilot and the couplers. So Bill, the owner showed up , two minute later said it's alll done and fixed and asked for 250 dollar . I paid as I needed my oven fixed professionally.
Two days later one of my worker tried to turn the oven on, and it blew up , burning his hand and face. The poor guy stayed in the hospital for a day and out of work for almost two weeks .
I tried to call bill many times and everytime he will say tomorrow and tomorrow . Lately he stopped answering my call.
I called my lawyer and we agreed that this Bill guy deserve to be put away.
