Vehicle in for repairs no response

On the 17th of December 2015, I was involved in an accident and notified my Insuarance on the same day which they arranged for the vehicle to be towed to SMD whiteriver, theni sent them all the required documents within three days after the accident. i phoned on the 5th of January 2016to find out as to wheather they have started with my claim or not, then i was notified that they only approved the claim on the 5thJanuary 2015.Since the I hav 5th of January i have been t contacting them trying to find out if they have started with repairs on my vehicle but i have not been getting clear answers. my question is how can it take the whole month to order parts. i dont understand why should i wait for tis long for my car to be repaired, even if i had car hire, you would have taken it back by now, so what do you think im driving at the moment ,cause i am using the vehcle to drivie to work and back home daily. iIfeel that this is beeing delayed for no reason and should arrange a cortesy car for as long as you are busy trying to repair my car. last week Chris Craft sends me an SMS saying the vehicle will be ready in +-18 days, this is the same communication they have been telling me
