re: Miway - Beware of third party claims

On 14 May 2018 a Miway client smashed into my vehicle. I was stationary and was waiting to turn right into Scott Road, Waverley. Both her and I reported the accident to the Norwood police station that morning. I contacted Miway to lodge a claim against their client and am now being told that I need to wait for their client to pay the excess. Alternatively, I can send her a lawyer's letter demanding her to pay for the damages or go to the small claims court. The client knows that she was at fault. So why is Miway not settling my claim. I have been inconvenienced for almost two months and they are unable to tell me when they can finalise my claim. That is if they do so at all.
