This company doesn't even deserve a 1 star. I had someone come out to my house to inspect my back flow prevention device per St. Louis a County Code. While here, I asked him he could tell me what he thought was wrong with my shower that rattled when I flushed the toilet. He said he would check the faucet manufacturer when he was done. Well before I knew it he was up replacing things and had the shower all taken apart. At that point, I couldn't stop him - frustrated that he started work without my authority. The entire install took him 10 minutes on the shower - so I just figured whatever at that point. I received the bill three days later. 10 minutes of labor = $143 dollars. The part was $82. I felt like I was at the mechanic as a female. When I called they claimed it was a math error and took the labor to $60. Still was being over charged. I had to demand that it was $30 an hour based on their hourly fee on the website. I also called Moen and they said an average person can get the part for $45. Cordia then proceeded to tell me that since they are plumbers their price is $82 from Moen. Sounds like a bad business deal. Bonnie who I spoke with was exceptionally rude. She didn't get the point that I wasn't paying that much for a part that I never gave approval to be put in. I just received a second bill after telling her I wouldn't do bad reviews on websites if she just called it even. Well I guess she doesn't know anything about customer service because $82 invoice showed up. I hope no one ever has to deal with this company. It's really unfortunate when you have a local plumber so close and get treated so poorly. They are unprofessional when talking to clients on the phone and via invoice. The invoice I received has 3 misspelled words and multiple words that should have been capitalized. Just goes to show how they plan on running a business. There will be a report to the BBB and I plan on telling everyone I know what an awful experience I have had. Stay far away from this company.
