Delay in repairing 3rd party car hit by rental

On the 30th August a rental from Bidvest drove into my parked car at a local shop. The driver said he would pay for repairs but was away from home so please send quote which I did on the 7th September I sent the quote. On the 23rd August they said the claim would be settled in 48 hours. The insurance company sent a long misspelt list of documents needed from me to complete claim - amongst others my ID drivers licence and car registration which was delivered and I kept sending to them via email on the 3rd October I phoned to verify that all documents were received - yes it seems so. It is now the 26th October and I am still waiting. The claim in under R5000.00 for panel beating How long would it have taken if the car was a write off?
