Bad service

My car was involved in an accident end of January. I started speaking with AutoMagic Strydom Park on 01 February 2022. Proof of payment for excess was emailed on 07 February 2022 After delays from getting parts and miscommunication internally at Auto Magic Strydom Park, the car went for repairs on 03 May 2022. When I went to pick the car, later in that week, there was a part they did not fit as they said they do not have it. I have been following up ever since, they promise to phone me back but they don't phone back. As it is now, the car is not fully repaired and the question is, what other damage might be taking place. I am not happy with their service at all. The Auto Magic referred to address is: 22 Susan St, Strydompark, Randburg, 2125
