Sedgwick CMS

On November 9, 2015, an Avis Budget Group rental van hit my car in Austin, TX and caused a lot of side damage. A policeman came, filed a report, and facilitated the exchange of information (because the at-​fault party only spoke Spanish). The two guys in the rental van called their work supervisor to come down since he could speak English. The nice supervisor came and handed over their rental van’s insurance information. I sat in the parking lot after the information exchange and started filing the claim. Through the Avis website, I was directed to call Sedgwick Claims Management Services (CMS) to file my claim. The nice and patient Sedgwick staff member at the other end took thorough details and said it could take up to three days for a claims adjuster to be assigned and contact me.
I waited nervously with my phone on or near me ²⁴⁄₇ the rest of the week but no call ever came. I finally called Sedgwick again to get the contact information of my assigned adjuster and emailed him. My adjuster, Carl D., never replied to my first email so I called him the following week. When you call, voicemail always picks up. He seems pretty diligent about calling you back within a business day. Carl returned my phone call, got some information, and said he’d contact Avis to see if the at-​fault party had their own insurance or used Avis’ insurance.
Six weeks have passed since then, there’s no news, and my car is still damaged. It’s also started rusting.
Although my car has thousands of dollars of body damage, it’s still driveable.
Update:
It turned out that the claims adjuster was missing a 7^th digit of the license plate number and had trouble locating the rental. He also couldn’t find the police report. I later found out the police officer was supposed to give me a blue form to fill out which would make the police report viewable. The at-​fault party also hung up on the phone call. Anyhow, I wish my claims adjuster had notified me immediately when he couldn’t get information.
