restore interior

I hired this company to restore the interior of an antique Cadillac the work at first was good but as the job progressed became very poor to the point of not even finishing buttons fell off dash faded and curled up. Tried calling them for months could not get a return call sent certified letters they ignored them finally gave up and hired someone else to correct the poor craftsmanship I would not hire this company to work on anything I was proud of owning except for maybe a lawnmower seat
