I had a catalytic converter installed by these guys and it failed within the warranty period, but they wouldn't verify that it had failed; I had to go somewhere else to get a replacement. I complained to the Better Business Bureau and Mad Hatter would not refund my money; they offered 50% off some work they might do, but wouldn't tell me what work, not that I would ever go there again. The employees were rude and unprofessional during my complaint process, rather than respectful and interested in helping resolve a problem they were responsible for.
