"Had a technician come out to scope our drain line. He forgot the camera, so they had to return. The check was not cashed, so I feared this with all the fraud in the world this man had my check and could compromise the safety of it. Called 3X no return call Told me to call accounting and no one answered and the voicemail was not set up ??? Customer service is very, very bad. I would NEVER do business with them again!!!!"
