Accident claim

Good day I involved in a car accident on my left wheel which my vehicle was sent to renew it strydom park which my vehicle has been there for two months. Firstly my car was approved to be repaired using genuine parts which saliem from renew it claimed that it was not authorized by insurance. They where putting back broken hub,control arm and so forth . I spoke to onwaba from discovery claim which she provided me with the assessment report and I found out that everything was authorized with genuine parts. I was disappointed with this action and but still today I haven't got my car instead of genuine shock from toyota as per authorize they put monroe shocks which cost R1500 for two and they removed both of my shocks. I asked for my old shocks and I was told by saliem that they're discarded two weeks after he told me that he found my shock which was a monroe and it's one but they removed two. Which doesn't add up. I then said irregardless that old shock was what. My insurance authorized genuine please do as per quote. Still after a month no luck on my genuine shock. Two weeks ago I was told by someone from net assess that my vehicle 2004 model is old car they don't repair with genuine parts whilst me the owner of vehicle I but genuine parts and their assessor is the one who quoted genuine parts coz he saw that the car had genuine parts .This was a big insult as I'm paying insurance but I'm being treated like someone is doing me a favour. Two months without a car this is totally unacceptable. I then offered to buy the other shock myself as it was a problem. Still I was charged R5361.88 for one shock. I don't know what to do anymore as this kind of service is unacceptable. Of which why must I pay for someone mistake or ************* When I had a rental car I was called by Avis car rental to bring back the car after two weeks of use but my contract was for 30days reason being the car was sold according to the guy who called me. Following day I called them and noone was aware of the story of which Michael was very helpful. He had to find out what was happening and apparently he found that the car I had the disc has expired. He then organized another car for me . This journey haven't been pleasant at all. Please can someone handle this matter for as I cannot stand this anymore. When I call discovery asking for management can't find one it's either on lunch or sick leave. Someone has to take action regarding this matter
