Bad: I phoned Dent Doc to repair my front window cracks that were no bigger than a centimeter long. Technician, Alvin, not only showed up an hour late and not repair the cracks, but he drilled two bigger holes and created a 12 inch crack and did not repair them. Joseph, the owner, did not accept responsibility for his technician's bad work, and refused to fix or amend the damages. I wasn't told there was a risk to the work or asked to sign any waiver. I am still shock I was dismissed and treated very badly.. Improvements: The business was dishonest and did not owe up to their mistakes. I would not recommend their service to anyone if they are not professionally enough to correct their mistakes. Honestly, how would you feel bringing your car to get a dent fix and find out that the dent got worst because the technician made a mistake. Then the company refuse to fix their mistake and told you to deal with it. It's their mistake, they should be honestly enough to fix it!. Other: The owner didn't care when I told him I will report his dishonesty. He even have the nerve to tell me to get the window replace myself because it would only cost me $150. I would never bad month any business because I know how hard people work, but I just CAN NOT BELIEVE what happened to me and how I was treated by The Dent Doc. I phoned them up because of the Channel 51 recommendation. Boy, what a BIG LIE!.
