Car accident claim

Im insured Dialdirect and had a vehicle accident more then 2 months ago on the 25th July my car was towed on a flat bed Tow truck to Renew-it Greenstone. This was not my preferred panelbeater as i was asked to get a qoutation from my choice of panelbeater which i did, But they isisted the car be towed out to Renew-it when the car was actually able to be drive. I am still not happy with repair done on my vehicle after the car was returned i sent the car back the intercooler was not replaced as well as new fitted fog light loose and vacume pipe diconected. Now went and picked the car up again and car was making a terrible noise on start up and was told i must then afford to take it to my own mechanic to get a report on what the issue is under my own cost and time. I then sent through video and report and qoutation from my mechanic and now another 2 weeks later im still waiting on if they will replace the pump. This has been a very dissapointing service from my insurer as well as Renew-it greenstone its been SHOCKING and very time consuming
