  • Useless company

    denise J.

  • Excellent service! I highly recommend!

    AJ M.

  • My mistake for believing a verbal quote for a part would be submitted On my bill was over $200 more. Three months past and a postal strike, the envelope was placed at my residence mailbox without my notice and is never used as we have a post office box a week before Christmas bidding they were in transition. Also adding a $50 what I’m going to call a goodness Tax. Which was later removed. caution would seem to be required.

  • I cannot believe the unprofessional and disregard for not returning calls and the nerve to say that they are too busy for my business and even a quote. I could not believe the conversation I just had with now two of the receptionist I would never handle a customer in this matter everrrrrr. Avoid this company, too busy and useless to waste your time, money and energy on.
