I have been recently ripped off for $150 by a company called Universal Precast Concrete, Inc. The owner Mr. Dan Christensen asked me to texture a 3D rock model. I did the texturing and gave him the source file but he refused to pay me saying it was not upto his requirement wheres he has kept the source file with him and will use it for his business. So I hereby warn all you guys out there to beware of this cheat. It is shocking that developed countries like USA also has such cheap scammers getting away with hard earned money of service providers like me.
