a despondent customer

I had a car accident on the 19th of August. On the same day of the accident, I called my insurance reporting the accident. On the 26th of August, I received an email from the insurance approving my claim and I was instructed to take my car to Durban Central Autobody. On the 30th of August, on Tuesday, I took my car to the Durban Central Autobody for the repairs. When I took an insurance, I included a car hire for times like these. On the same day that I took the car for repairs, I took the car hire and I was supposed to return it back on the 29th of September. Upon checking with the Durban Central, I was told that the car has not yet been fixed as they are still waiting for the car parts, when I informed the insurance company about this, I was told that they can not extend the period for the car hire as it is only for 30 days, I then pleaded with them and they agreed to extend it to the 6th of October. I then checked with Durban Central Autobody on the progress of my car and they told me that till this day they still waiting for the car parts and they do not have a time frame for when it will be ready. I informed the insurance about this and they said that this is not their fault that it is hard to get Hyundai car parts and I should pay for the car hire out of my own pockets, I feel that they are not being fair. I am their loyal customer, I pay every month for my premium but they are not willing to help me. As it seems, I now have to pay for the car hire on the side, out of my own pockets while still paying the premium which means that I will be paying twice whereas this is also not my fault. I am very devastated about this. There is no fairness.
