Lies and being failed by Discovery insure

I had an accident on the 22 Nov 2018. I submitted my claim and was allocated a claim advisor(Simphiwe) and he advised that I will be contacted by a claims assessor within 5 working days. The claim assessor only authorized the repairs for my car on the 4th Dec 2018. Nu Wagon Autobody booked my car on the 5th Dec 2018. On the 12th Dec 2017 I called Nu Wagon Autobody to find out about the status of my car and I was advised that my car has been stripped and they still awaiting other parts from the supplier and I asked them if they will be closing for the Dec holiday break and was told No they will not be closing they will be open through out Dec holidays. I got a called from Nu Wagon on the 17 Dec 2018 to be told I need to bring my car in for repairs on the 7 Jan 2019 and I told them that my car was at their assessment center since the day of the accident (22 Nov 2018) and I asked if you saying I must bring my car on the 7 Jan 2019 meaning my car was not stripped as mentioned to me. The lady said she will call me back and never called back because she knew that they were lying to me. regarding the repair of my car. I then decided to call Nu Wagon Autobody for their phones to ring and no answer by then I decided to drive and go find out what's the status on my car. Only to learn that Nu Wagon will be closing on the 21 Dec 2018 and they will re-open on the 7 January 2019. I asked but why did you guys said you will not be closing and now all of a sudden you are closing. Then I asked to see my car as they mentioned it was stripped and they were awaiting some more parts only to find my car gathering dust at the Help24 towing yard, with my left front window open for days and weeks and to make matters worse it was raining for the most of those weeks. I then asked when will the car be repaired as now I am told lies and lies, only to be told that they are still awaiting Authorization from Discovery insure of which I told them that discovery authorized the repairs on the 4 Dec 2018 which authorization were they still waiting for... I couldn't get answered from the guy who took me to my car. I went back to the Nu Wagon reception to tell them that they have been lying to me regarding the repairs, stripping and awaiting parts for my car. I then told them my car window is open and has been open now for days and weeks now only to be told that they will request the car to be towed to the repair center. I told them that I took pictures that I will be sending through to Discovery for a claim I will lodge for my interior damage. I then escalated Nu Wagon to Discovery insure on the 17 only for Nu Wagon to respond and say they received the last parts an hour after I left their offices how convenient and convincing. I was assured by Juanita that Cobus has requested for the repairs to start the next day. I was told again that I will be getting status feedback regularly from Nu Wagon. On the 21 Dec 2018 I decided to call Nu Wagon again as I didn't receive any communication from them despite them saying they will feedback. I was offered a courtesy car for Free of charge until they re-open on the 7 Jan 2019 as my car was incomplete and the rental car was due back on the 22 Dec 2018. A courtesy car was delivered on the 21 Dec 2018. I then gave them a chance again for them to contact me and provide status update when they re-open on the 7 Jan 2019 and I got no feedback. On the 8 Jan 2019 I decided to send Nu Wagon an email to find out about the status and received no feedback. Faith from Discovery insure sent them an email too as she was battling to get through them via telephone and 4 hours later no feedback. I decided to call them and find out for the call to be answered by Help24 and to be told that Nu Wagon will only re-open next week and again i was **** to by Nu Wagon. I then escalated to Discovery insure via email and telephone as once again Nu Wagon has failed me and **** to be again. I am humbly asking Discovery insure to please move my car to another repair company or Autobody as Nu Wagon is lying to me and to think I have never skipped any insurance premium and I still paid 2 months premium for a car that is still gathering dust and not repaired. Discovery insure I am pleading with you guys to do justice to me as I have an 18 month old child that I need to transport comfortably with my car.
