I called company for plumbing service and now sitting in despair with a damaged ceiling and still with a unfixed faucet for more than two weeks in my 2 years house because of their plumber's negligence. I called a company's plumber named "Mark" two weeks(September) ago to check the cause of a water stain on living room ceiling which i noticed 2 days ago. He came and told me that stain on the ceiling is because of a leak from the shower faucet in the bathroom above. He put silicone on both shower and tub faucets ''without checking tub faucet ''and left in 5 minutes. He charged us 300$ for coming and just putting the Silicone in 5 min. When we opened the shower faucet after 24 hours as being told,our ceiling ripped open and water start pouring down from living room ceiling. I called same plumber again and this time he told me that leak was from tub faucet not the shower. when i asked him in distress that "why he did not check the bath faucet in his first visit?" He did not give me any satisfactory answer and left. Desperately i called my insurance company for damaged ceiling. They estimated the damage between 6000-8000$ in which 2500$ i had to pay. In total agony i called the company to talk with manager on Friday. When nobody called me back i called again on Monday and left message again. On Tuesday Manager called and i told him the whole situation. He said he will send someone to inspect. Another person from company came on Wednesday and after inspection said "it is misdiagnosed and ceiling leaks after that is a normal thing" I was shocked to hear the arrogant response from company's employee. Now i have been trying to call manager again for few days but he is not responding or calling me. I will wait few more days and then i will file a law suit against this company. I am really disappointed in this company's negligence and attitude and advise every one to think wisely before calling their plumbers.
