Disgusted by repair work

I am extremely disappointed by this company. Last year I went to fix my bumper that broke due to a negligent driver. Dent Doctor Honeydew claims that they put on a brand new bumper (which was quoted for), but within a few months it already came off (damage to the brackets looking exactly as it did before the so called repair job). I even had to get a second opinion from a trusty mechanic of mine who agrees that the old bumper was just repainted (which was also a disgusting job). I would advise anyone who thinks of going to Dent Doctor to think twice.
