Miway fixed my car which even their own panel beater which they later referred us to in midrand refused to touch the vehicle saying a ****ty job was done by Precision(Car is giving issues as per that panel beater advised and now claiming its not accident

It is the 3rd of January 2023 to date I'm having issues with the car and this insurance don't want to assist when I tell them the car has issues, I'm asked what do I want them to assist with???? The car is giving issues after issues after issues ever since and no1 wants to take accountability...just last week it was in with BMW waterfall and after we paid on our own as we had to attend to our brother's funeral using the same vehicle (which we want to be reimbursed) again the vehicle is giving issues, the boot reopens as soon as we close it(which then unlocks the doors) but again no1 wants to acknowledge that all this is caused by the accident Precision Auto did a ****ty job on the car from the onset and Miway should sort it out with them. I have been doing the ping pong for a while now back and forth from Midrand to where Precision is located it is not fair (Car has been sent back over 6 times with issues). I WAS INVOLVED IN AN ACCIDENT IN NOVEMBER 2021 BY THE WAY: C*** now boot doesn't lock (boot shocks were changed, bumper was damaged but now Miway is claiming it's not accident related)
