Europcar Accident

I always rent from Europcar or Tempest but after this situation I will be taking my business elsewhere. In July a Hired vehicle from Europcar crashed into my vehicle. I went through all the nessasary steps to log a claim and informed Europcar on all the details. After back and forth with not much response from Europcar unless I asked questions. I recently got a email to say that the renter of the vehicle didn't make contractual obligations so I am liable to pay for my own damages on my car. I was parked and he drove into me. Im aware of the signing thats takes place for damages.

5 months to tell me that they will not be paying for my damages. But very quick to charge you for any damages. I would like a full report on this matter and I want more answers than just a rude email from someone saying they won't be paying.
