Terrible Service

Took my car to Blue Tech panelbeaters in Kempton Park after my insurance approved my claim , that was November 2021 , and on the 6/12 was told to collect my car, the car bumper is not fit properly , car did not start as per normal , body paint was not polished , gabs between the bumper and bonnet was too big , i have been going to their workshop and till today my car is not up to standard, the bumper fitted is missing *****s and loose ,now i have to replace Front shock because they did not include it on quotation to my insurance
