Guest hit me, now Turo will not respond

So 3 weeks ago, a Turo "guest" rear ended my parked vehicle, damaging the bumper and rear corner. The Sheriff gave us both an incident report, and sent us on our way, since damage was not major. The Guest will now not answer phone calls from me. Turo claims dept. has requested the information 3....yes 3....different times (which I have provided every time). Now Turo claims dept. will not return emails (and I have no phone for them). I need to have these repairs covered by either Turo or their Guest, obviously.

I am reading that I have 2 options at this point:

1: File a collision claim through my insurance (no-go as my deductible is higher than the estimate, and I apparently do not have coverage for this particular scenario somehow, even though I have full coverage)

2: Sue in small claims court. This is apparently the option I will have to take. I now need to determine if I will be going after the driver/guest, or Turo themselves. Guess I need an attorney at this point.

So I am wanting to make it known to everyone that Turo is a horrible scam of a company! They do not want to honor their liability when their drivers cause an accident. They do not contact people filing a claim. They apparently want to hide away and hope their problems just go away.

Has anyone else encountered this scenario before, and have advice on how I can proceed to get my car repaired? Anyone know an actual phone number for Turo claims dept.?
