JD Precision Plumbing Services, Inc. Replaced water main valve Conroe Texas

 DO NOT call JD Precision Plumbing, they are modern day Pirates. They charged me $800.00 to replace this one small section of water main and valve. took every bit of 30 minutes. They say free estimates on their website. When I called for service, I was told there is a $175.00 service call charge and would be I would be credited this amount if work is done. I'm thinking it cannot cost much over $175.00 to fix. (wrong). They estimated $791.00 to fix it. I'm not home due to a surgery and have buddy relaying info to me. I think ok, the $791.00 less the $175.00 so $616.00 to me. (wrong again). I not only get charged 791.00! they added 3% for using a credit card. Now I'm at $815.00 to fix. I try getting justification on charges from their operations manager only to be told JD Precision plumbing is so big and they have higher overhead than any other plumbers, therefore have higher costs for service.
