Over charges for service! Asked the service tech what would be the charge to fix and I thought he said $45. When I get the bill after the work is complete it was $485. When questioned about not having the rate in the preauthorization I was told he always put the rate in after completed. I called the office to address and was told someone would call me. No one ever called I had to call back. When questioned about the rate was told it was a fair rate. I told him I disagree and his tech did not have the rate on the preauthorization and I thought he stated $45 for the install. This is a $50 part and the tech was at my home for maybe an hour and the installation took maybe 30min. Even if you allow a mark-up on the part and include the service call fee this was should have been $200 at best. Service manager would not do anything stated it was a fair rate! I will never use this company in the future. Top it off it wasn't even the problem!
