Spartan Services LLC review: Failure to complete work or provide warranty service

I had a septic system installed by Spartan Services LLC (Sparta TN) in my new house in July 2020. It began leaking on first use. The owner (JD) came out to inspect it a few times but never came to actually fix it. I finally determined the cause of the leaks through my own troubleshooting (putting different dye colors in the settling tank and pump tank) and was able to trace the problem back to the settling tank. During the troubleshooting, I also noticed a leak on the pump discharge piping that feeds the leach field. I want the settling tank pumped out, inspected, and repaired or replaced and I want the supply line repaired. I paid for a new system and am tired of sewage running down the hillside. They will not answer calls or texts.
