How do you dispute auto accident repairs from insurance company?

A dispute of repairs resulting from an accident should be directed to the Shop that made the repairs. The insurer is responsible for paying for the agreed amount for the repairs. However it is the Vehicle owners responsibility to choose a reputable repair shop of choice and the Shops responsibility to provide a quality of work acceptable to the vehicle owner. The insurance company who paid the repair bill is not further liable for poor quality of workmanship ptovided by the repair shop nor for a poor choice of repair facility on the part of the vehicles owner.
