Disappointing service from outsurance

I was involved in a front car damage accident, the outsurance assessor assessed my car at towing company site whilst I had my car keys on me. How could he possibly had made the initial assessment accurately. I was provided with only one quote for +- r20 000 at Felix auto shop Athlone. My car failed quality check due to alignment issues but then on 03 August was told I can collect and the car hire expired. On review on the car I told who can I speak to because this bumper looks flimsy and the black lines between the fender and bumper can be clearly seen. The woman brought out the book and stated what was fixed. I said so nothing was damaged inside the bonnet. So IL be fine to drive this car. I was assured. On 05 August 2023, heard creaking sound under the left side of car, to my horror when I looked there was black broken attachment under the car the whole under structure not secured with a ***** loose at the bottom. From there it has been a hassle for outsurance to get their assessor to come view what they let me go home with. I had to take a leave day from work because I had no car hire and to make numerous phone calls because outsurance don't get back to you. The Monday, the car would not start, the display lights went on, despite the car keys being on, making sounds. I had to call the emergency outsurance to get the car towed away. A car hire was given to me , and then I got a call from car rental saying your car rental is expired only 2 days later, should be in within20 mins. I was so shocked I said no one informed me as I still do not have a car. Tried calling outsurance, I was told the relevant department will call me back. A day later I get a sms stating the car expired the day before at 10am!

I have never in my life been more inconvenienced. My safety has been compromised. I have to make endless calls to outsurance. I won't be able to get to work without car. This process has been more traumatizing than the accident!
