Gerber Collision & glass Failed to repair my truck after 2 month still figuring it out Livonia Michigan

 Horrible customer service. Has had my truck since June 20, 2016. They did body work first and fail to check engine when I told them it had a noise after the accident. Now supposedly I need a new motor my frustration is that all this information should have been on orginal quote so my insurance is aware that we have to have a new motor. On top of all the body work. So they have a chance to total the car instead of paying for the body repair than finding out motor is bad now and needs to be repaired because you failed to address it. I firmly believe that my insurance company would of totalled the vehicle if they where aware of the motor as well as all the body repair. Now it seems like I can't get any answers seems to me Jeremy dropped the ball on the over all estimate for my insurance company. Now it seems kinda weird he no longer works there.
