I had an already frustrating experience with budget insurance in trying to get my car repaired through a third party claim. Eventually I was referred to automatic in Paulshof who would repair my vehicle. They called me to make arrangements to bring my car in. They suggested they pre order the parts so I would be without a car for less time. It's been three weeks. I have called them on two occasions for an update as well as a request for the manager to call me to find out what the status is on the parts for my vehicle. The manager has not called me. The service is unfriendly and unhelpful. I am bewildered as to how companies like Budget Insurance and Autimagic - survive!
