Traumatic experience

How long does an insurance claim at Standard bank take? I was told by some of my friends that I should stay away.

My brother got into an accident in February, he was stabbed and knocked out... so traumatized that he has little memory about what really happend and is going through cancelling for it.

The insurer on the other hand sends him from pillar to post explaining to each and everyone again and again what happend.

They told him they had bean and billing a month back, when he came back he told me they said it isnt there and his claim will be handed to someone else again.

Is there anyone who can help him??
