North Texas Custom Plubing, John Carter John Tadlock , unprofesional "profesionals" Celina, Texas

I had John Tadlock of North Texas Custom Plumbing out of Celina TX, come to my home and redo all the plumbing. Not only did the man and his day labors mess up my gas line, but they didnt even install the pipes correctly. Now when the washer is on, it backs up to the toliet, causing it to flood. Also had a sink put in for future us in my utlity room, he never even put a drain pipe in the room? How am i to turn on the water but have nowhere for it to go? Seriously this guy has no plan... dont ever pay up front, they left me high and dry, i had to hire another plumber to fix this mess. Cost me more than it should of.
