6 mnoths without my car

In August 2014, i launched a claim with virgin insurance which was approved and my car was taken within 2 days. The car was scratched on the front and the passenger side whilst it was in a parking area. After a month the rental company called to let me know that i had to return the vehicle. i then called my insurance and i was told that they had been trying to get hold of me, my car was ready for collection. When i went to the body works it was only fixed on the front and the side looked the same as it was when i took it in. After enquiring i was told that the assessor said the other damages were old and they will not be covered by the current claim. I asked him how he came to that conclussion on the mirror holder and the left side of the rear bumper which was not perfectly intact, he could not answer but kept on pointing on the scratches with rust. i asked him to fix everything and leave the rust. with that he refered me to the claims department. I spoke to Paskal, then to her manager Jason van Niekerk who i sent the photos. He agreed to talk to the repairs dept to correct the repairs that were not done properly but later denied saying that. i have not yet recieved my car back
