Standard Bank Insurance Brokers

I had GIT cover with Standard Bank. I had a claim in August 2020. My GIT insurance did not pay. Reason for non payment is that there is no proof that my vehicle was in roadworthy condition at the time of accident. 10 months later they say they need proof. What proof do I give them 10 months later. An inpector was alocated to inspect the vehicle in March and April 2021. After seeing that the report confirms the vehicle being roadworthy, they are now looking for reasons not to pay. If they knew this was a requirement shouldnt they have inspected the vehicle immediately after the accident?
