Hello! I was rear ended, and the other party was liable. I submitted my vehicle for repairs at the shop of my choice. The car has been in the shop for way longer than the estimate stated due to shortage of parts. (Estimate was approved for 20 days, and its been almost 5 months lol) Adjuster stated they wont be covering the rental because it was excessive. I know that some shops are not truthful, but I confirmed with Acura. The parts were genuinely on back order the entire time. I told the adjuster that its not my fault that Acura is backed up, and that I wouldnt be in this predicament if their insured hadnt hit my car. He insisted that they wouldnt reimburse me for the rental. Side note: Originally the adjuster estimated approx $9K in damages, and the shop was in the ball park of $21K in damages. When the supplement was issued, the allotted time to repair still stayed at 20 days, is that normal? My thought process is that if there was more damage, then it would take longer to repair lol. What do I do? If I seek legal assistance are the odds in my favor? Im in Illinois if that helps.PLEASE HELP
