SANTAM is playing delaying tactics with my claim

I launched a third party claim with SANTAM insurance on 22 January 2016 following a vehicle accident with their policy holder that occurred on 8 December 2015. I was initially told that their assessor will go and assess the vehicle damages in February 2016 and be given feedback afterwards. Up until today(15 April 2016) when I call SANTAM call centre I am always referred to Lokash whom I cannot get telephonically so that he can tell me exactly what is causing the delay to carrying out repairs on my vehicle. And I have been unable on a number of occasions to escalate the challenges in my claim to his senior (Retha) as she does not pick up her telephone or if it gets to be picked up am only told that she is in meetings. This has caused me a lot of stress as I have to perform my duties at work using this vehicle. And they have not shown any sense of interest in dealing with the matter speedily. From 22 January 2016 until now (i.e. 15 April 2016) there has not been any direction as to when will my vehicle get to be repaired. No communication from their side to say how far they are, am the one who has been doing the chasing after. Kindly assist me as am on the verge of loosing my job.
