6 MONTHS - VEHICLE IS TILL NOT OKAY

I was involved in a car accident - 31 May. My car was assessed and sent Auto Rust (Warner Beach). They did the fix. But since then I have been having issues with this car-same side where I was hit till today my car is still not 100%. They keep sending me back to Auto Rust or DBN south Toyota. Today is one issue , next day it's another. Vehicles carry our lives , my kids' lives. I cannot afford this risk I am taking now. Driving a car with strange noises. I think the Assessor did not do the good job , underestimated the damage , because as it stands , I honestly think the job that needs to done in this vehicle is still huge. Yet I am driving it..on the road everyday - ticking time bomb. I will write the same about Auto Rust , they get very annoyed when I keep knocking at their door with a different issue everytime. PLEASE HELP!!
