Nedbank insurance or ************

I had an insurance policy with outsurance and I was contacted by Nedbank to change my insurance to Nedbank insurance at a lower premium as. I bank with nedbank. They gave me a quote I accepted they started debiting my account. Few months down the line my vehicle was stoned. Its three weeks and nothing has been done about the damage to my vehicle. I have called them a few times a week to hear different excuses as to why my claim has not been sorted or declined. On the last call I got told that my claim was sent back to assessor to remove the rollbar which is an accessory on my vehicle. How can it be an accessory when I bought my vehicle second hand with the rollbar fitted. None the less Nedbank is a poor excuse for an insurance company. I wouldn't advise anyone to insure with them. Im actually feeling like changing my bank whilst changing my insurers
