Avis review: My personal car damaged by Avis employee

Avis employee at Shenandoah Airport in Virginia (SHD) backed into my parked car on 28 September at approx 2:30 local time while I was away in Europe. I learned of the incident from the Airport Security Officer who called me at 11:30pm (Italy time). No one from Avis contacted me even after I requested the owner of the Avis branch to call me.

The insurance company (Avis Group/Sedgwick) has been less than cooperative and has taken a long time to get my car damage appraised. No appraiser has visited me - and they asked ME to photograph the damage and email it to them. The estimate of repairs was for use of aftermarket parts, and I would like the car returned to pre-damage status with OEM parts. The insurance company refuses to include compensation for inconvenience - my car is my primary means for visiting my sales customers and my body shop cannot get me in for repairs until December. This entire experience has been awful, and I am considering never using Avis for my rental car needs (I use Avis/Budget exclusively for many years).
