Insurers unjustified delays in paying-out flood damage claims

My vehicles were damaged in the April 2022 floods at a workshop-Shannon Auto Repairs in Durban. The brokers -Bawa Insurance Brokers -managed by Stategic Insurance Sytems requested documentation from me in April 2022. I submitted the documents in April 2022 and have not received any correspondence from them since. The Insurer -Mutual and Federal -have not responded in this regard either. They have paid the owner of the business for his machinery and equipment that were flood damaged, on the same premises, where the vehicles were parked, but have not paid out the claim for the vehicles damaged. The business owner assured me that he has insurance cover for all the vehicles on his premises. The business owner has instructed me to remove the water damaged vehicles from his premises as the Insurer has not responded. This has financial implications for me in terms of towing and storage. This delay has impacted on me negatively. It's almost 7 months, and this delay in response from the Insurer is unjustified.
