Waiting on the claim recovery department

I have a claim that is still sitting in progress from November last year. I am awaiting feedback from the 3rd party, whom I was told by Discovery will pay for the entire damage to my vehicle. I do not get any feedback from Discovery regarding their recovery of the excess. I have to always phone in, on many occasions to an on-going ringing phone. I gave them all the information about the 3rd party, but they are still unable to get a payment. Surely it cannot take so long to have this sorted. Now I have to drive around with a damaged car until they get payment from the third party. Not acceptable. Is the recovery department not able to request this legally?
