Best Switch Replacement in Philadelphia PA

Scheduled a sewer inspection. I was not home, wife was home. I was told the line was holding 25ft of water and it was rotted out. Repair cost $4350. Came home from work and watched the video provided by them and barely seen any water in the line or any rot. Had another plumber come snake the drain and clean it and record another video. He says the drain is fine, no rot, no water, just some grease build up. McClain said they would come back out 2 days in a row to look at it again and never showed up. DO NOT USE. Trying to SCAM people and do unnecessary repairs. Not trustworthy at all.
