Does not want to give update on my Brother's car

My Brother had an accident in Durban. He is insured with Absa Insurance, he has been trying to contact Allan who is handling his claim. Allan keep on giving him a run around. I intervened on the matter and Allan last Friday told me he is going to sort this matter out by today, now I called him this morning he said he was going to return my call before the end of the morning. the morning ended, Allan did not return my call. I have tried to call him, his phone is now off. I am worried as to whether Allan knows where is my brother's car. If he knows I don't know when is he going to approved for the car to be repaired. The sad thing here is that my brother continues to pay for the car that is not being repaired by insurance. The car is seating in a yard somewhere. My brother's name is Bonga, Surname, Chamane. Allan's number is ***
