My car insurance 1st class garage (understand that garage) ok. I was hit by the car, was stressed that the party was right. Then took the car in for repair and there was a way of insurance telling that There are 2 pieces that have to be 2nd hand stuff, I'm not okay, so make sure the way is stable, order 1 hand and then the difference is me out. Emphasize that only 2 pieces are the hood and the front bumper. And the car was repaired for a month, I was informed that the insurance had asked for extra money Because there is still a difference that Honeycomb air conditioner panel again. I'm confused. The car has been completed for a long time Still have to pay more. Confused why do not you collect the difference that the other party is at fault? Like this must be long, I would like to consult # OIC first. Very bad. Used for a long time. Many cars are not as bad as this.
Who will use this company insurance? Think carefully
