Had my car there for repair. A collision that was not my fault mind you. The estimation was for 3 days. The fourth day I get a call from the insurance telling me they are not paying for the rental after the 3rd day. Finding the contact person at this place was mission impossible. I left messages and finally she calls telling me they are waiting for a part to arrive, something that should have been notified to me. My car was drivable. Finally when I demanded to speak to the manager she calls me back telling me she already called the rental place and renewed the rental agreements. Guess what I ended up paying for the rest of the car rental. It was an additional 7 days. My sanity is more important so I gladly paied myself than deal with these people.
