Great South Autobody doesn't care

My name is Dorothy, i got an accident on 29 July 15, a lady beat the robot and i got hit.my car was towed to Great South in Booysens from the scene. I liased with my insurance, KingPrice and was told Great South received authorisation to repair on friday 14 August and called them monday 17 Aug, i spoke to a man that said they didnt receive anything which is a surprise because when i called them 2 weeks before i was told my car was assessed a long time ago and when i ask why is it taking long was tols its a mistake there was a car exactly like mine there..i am extremely upset at the lack of sense of urgency. I didnt cause this accident but i'm at the receiving end. I call the dealer atleast 3 times a week to check..other times i get put on hold and then hung up on.i'm ready to pay excess because i need my car but i feel like i'm the last person they want to assist :(. I dont know how quick they can repair my car but they dont know either because nobody can give me accurate fredback..i call them and an hour later my mom will call them and we'll have different feedback.i only got some sort of assistance from a lady called Carmen. I am very upset :(
