Extreme Poor Service From Auto & General For The 3rd Time Now

I had an accident on the 4th of September,I had car hire for 30 days and was promised that Auto & General & the panel beater being Auto R would have started repairs on my vehicle. Yesterday marked 30 days and they are still not passed my vehicle being assessed and I have to return the car hire.Yesterday I received an sms from Auto R saying that they are awaiting parts for my vehicle. Upon calling today I was told that an assessor is going to assess my vehicle again for the third time. Between Auto R & Auto & General someone is not telling me the truth. One company is awaiting parts to begin repairs on my vehicle the other is still busy with the assessment. Both companies have inconvenienced me today as I have no vehicle to transport me to work. The assessment and repairs of my vehicle has been delayed AND Auto & General refuses to extend my car hire. What kind of service is this? Why should Auto & General always inconvenience it’s customers when they have to assist them? This is happening for the 3rd time now!
