Still waiting to hear back

I put in a claim for accident damages to my vehicle a few weeks ago. The questions I was asked at ti?me of claim made me feel as if I was being cross questioned. After dealing with the assessor, Coenie, I felt more comfortable about the claims experience as he was helpful and friendly. My claim was approved and a repairer selected for me. I requested a change in repairer on 27/08 and received a mail saying the change will be sent through and I would get feedback once it was done. After a few emails and a call I still didn't receive any feedback. On Friday last week I decided to call Coenie who assisted with the changes. He then informed me my claim assessor Hlengiwe would need to proceed on her end however I have still not heard back yet. On my call to the claims centre I did mention the inconvenience of not knowing when my car would go in as I'm not sure whether to top up my tank with petrol because once I do my car could be sitting at the panel beater for a while. I'm also in a lift club and I use my car on certain days and I'm not sure which day I will be asked to take my car in. This is my 1st claims experience for accident damage and it is awful, so much for claims made simple
