Insurance prefer supplier-canceling due to that

Having dealing with this group has been the worst experience of my life. They delayed the approval process by 2 weeks. They provided me with a quote via email, I rep**** asking if this was submitted to my insurance I did not get a response. I called for 2 weeks daily just to be told someone would call be back not once did I receive a call back. I then asked to speak to a manager as I was not happy was told the manager would call me back to date no call. My car was towed from the Sandton office to the Wynberg office without any notification. This is a brand new car no number plates yet. I finally get it back and they have not put the number plate bracket back, sorted now. The side with the damage, the door does not align with the side panel. After taking the car back they said they would fix it, I waited 30 min later I get my keys back and was told that they aligned the door on the side that had no accident damage as the side repaired is fine. This is a brand new car why touch the side not involved in the accident. My door is still not aligned, I left before I did something I would regret as I was fuming. I am ready to cancel my insurance as this is there choice of servic
