The team installed a water heater at 3443 20th St. Apt B a few months ago and after running into issues for multiple months, they showed up once to reset the water heater which begain failing again a day later. After many phone calls and messages, they have yet to respond and are completly avoiding me.
It's really sad and frustraing to see this contractor not honor their work and warranty.
