Unacceptable service. Not doing their jobs with admin. Worst ecperience ever

Me and my daughter was in an motor vehicle accident on the 3rd of October 2017. My car was towed as a non driveable. I was admitted to hospital for 3 days. My husband only got any feedback from MiWay on the 11th of October. Stating that our Claim is accepted and that my car will be fixed on 12 working days. We calculated 12 working days and the 12th day would have been the 27th of October this Friday and we arranged things and made plans for us to be without my car for the 12 working days. I called the panel beater on the 23 and 24 th to enquire about my car. Only to hear that they did not yet receive the approvalfrom MiWay for my car to be fixed. My car was standing there for 3 weeks, the panel beater enquired about the approval and so did I. Only after having to call and yell and be upset sis we receive an email today stating our claim has only now been approved and that my car will only be ready by 24 November. We have 3 children, that need to get to school and after school activities, my husband needs to get to work and I need to get to my meetings and responsibilities. We do not have any more resources left to help us untill my car is fixed. After I stated this to MiWay did they come back to us and offered R1000 of off our excess to help with car hire. Do you know what car hire costs. We can get a much smaller car than my nissan X trail for 7 days for R1900. What about the other days until the 24th? This process is taki g extremely and uneccesary long and this is unacceptable. Someone on MiWays side did not do their job and send the approvals for my car to get fixed and because of that we have to be inconvenienced for much longer than neccesary and that is unacceptable. We didnt get any feedback from MiWay before the 11th eventhough the accident was a week earlier. I had to call them and remind them to do their jobs and that is unacceptable! Worst experience ever, now I have to struggle without a car until the 24th of November. Unacceptable
