Business ProfileforRoto-Rooter Plumbers

When we moved into our house about 2 months ago, we noticed that the upstairs sink gurgled when the toilet was flushed and also had some odors at times. I called Roto Rooter to come out and fix the issue. They arrived and took some info and said the "sewer line needed flushed/cleaned out." They "cleaned" out the sewer line outside and after said the line was actually really clean and they would need to go back to the office to get their camera because they didn't bring it to diagnose further. They charged $280 for the clean out of the line that wasn't the issue and another $280 to go back to the office and get their camera to come back out which made no sense. They came back and used the camera and couldn't figure out the issue, which seemed very incompetent. They said the issue was likely from the roof vent being blocked but the guy said he was afraid to get on the roof. They then sent out a different crew about a week or so later and said the vent pipe was blocked and needed "hydro jetted." They said this would fix the issue and charged me an additional $720 to hydro jet the vent. The guys did this and still didn't fix the issue. They then told me that they would need to tear into my drywall and have the vent pipe either repaired on replaced which would be thousands more. The crew said they would be getting back with me on a quote and never did. The company seems to be only interested in price gouging me on issues I don't understand.I have now spent almost $1300 to fix an issue that should've been fixed when the first crew came out and still the issue isn't fixed. This is ridiculous and negligence.
