Complaint against faulty tracker fitted by netstar

I got involved in a car accident December 2019. I reported the accident to my insurance dial direct. They took 2 months in finalising my claim. I had to constantly call them for updates. In December 2019 they towed my vehicle to vw for assessments my vehicle stayed there for two months as dial direct refused to grant vw permission to conduct the assessment, my vehicle then went out of warranty. Dial direct then wrote off my vehicle without doing assessments. I lodged a complaint with their internal dispute resolution. Dial direct advised that they can now repair the vehicle. They took away the car hire. So during this pandemic i travel by taxi with my sick daughter to doctor appointments. I am unable to also work because the industry i am in as a consultant requires a vehicle. Ombusman took 5 months to give an outcome and yep they were biased and ruled in favour of dial direct. My car tracker was faulty and not working since October 2019. I called and emailed netstar on numerous occasions to sort out the issue, they have ignored me to date. They should be liable as i drove my car with the impression that my car and i would be a bit safe with tracker and a panic button. If i had a functioning tracker in december 2019 it would have been easier for dial direct and I to finalise the matter
