My home and vehicle insurance is with Nedbank

My home and vehicle insurance is with Nedbank. On the 30th March 2026 I tried to put in a claim for my damaged rear door handle of my vehicle. I only managed to get it approved by the 8th April 2026. I already had quotations from various certified bodyshops. They told me that they use their own. The body shop they told me was going to contact me to take my vehicle in for assessment. Only after I contacted them I was given a date for assessment which was the 18th April 2026. After the assessment I was told they will order the parts and let me know when to bring my vehicle for the repairs. Again only when I called them they gave me a date to bring my vehicle for repairs which was the 18th May 2026. I dropped my vehicle on the 18th May 2026. Later that they I asked them how far the repair is as it is only the handle that needed to be replaced. They then told me they ordered the wrong parts. My vehicle is still not repaired.
