State Farm review: Auto hail damage handling

I'm dealing with 2 claims for my brother-in-law which State Farm illegally steered from our repair facility in a recorded conversation. The first claim number is 53-56Q793B and the second claim number is 53-56Q798J. These claims were submitted nearly 30 days ago and he still does not have an approved repair estimate on either vehicle. State Farm refused our estimate and stated in a recorded conversation that the vehicle appeared to only have roughly $2,000.00 in damages while our written and documented estimate was roughly $16,000.00. They forced him to go to their DRP for an appraisal and Classic Collision agreed with our estimate and even stated while being recorded that there estimate would probably be a little higher. They then had a PDR company that is directly linked with State Farm to write a roughly $8,000.00 PDR estimate and then stated he couldn't repair it but the body shop could repair the additional by filling it with bondo. The vehicle obviously needed the panels replaced or both facilities would not have agreed and one of the facilities is State Farms chosen DRP for an appraisal.
