Best Main Sewer Stoppage in San Antonio TX

This is by far the worst plumbing service in San Antonio, I made the mistake of not reading the reviews before I hired them, don't be like me. Plumber came over and determined we had a leak on the main line  due to tree roots. Plumber worked for about 4 hours (tried billing me for 5 plus excessive material) at 175 dollars per hour,  the leak turns out was not fixed nor properly identified and continues. Their office does not respond or follow up after calling them to fix their mistake. Zero stars if I could.
