Annoyed

My car went into the panelbeaters on the 19th December 2019 to be fixed as my door handle was not working as it was broken into, My claim was approved on the 8th of Jan. I only received my car last week Tuesday, I have been given the run around by the panelbeaters and the insurer. I am extremely dissapointed with this insurance company and will be moving because as i am typing this my car is worse than before it went into the panelbeaters, they fixed the door and managed to mess with my gears and opened up where my airbag is supposed to be, i dont even know if the airbag is there or not. I emailed the panelbeaters and the insurer, the insurer has not responded to my email. I don't understand how they approve such panelbeaters who cannot even do a proper job because now i am left wondering what else is wrong with my car.
