No feedback / update on claim unless I call them

I was involved in an accident on the 10th December 2015 and lodged a claim with Santam (***). In my policy, I do have the car hire option which I have been using since the 11th December.<br> <br> To cut the long story short - I have totally been dissatisfied by the service I have been getting from Santam thus far. I hardly get any calls/feedback with regards to my claim from you guys. All I know is that my car has been written-off and there are follows ups that have been made. My claims handler is Jenette Botha who is now on leave till the 25th Jan and the very same applies to my assigned assessor (Kallan Scheepers). Was assisted by a lady named Carina Boshoff (been trying to contact her with no luck today). I have been trying to contact the above people today (4-Jan-15) and have also sent emails but to no avail. I wanted to request that my courtesy car rental be extended till the maximum period allowed (30 days) - Currently on 24 days today but can't get confirmation that this will be done. Further - I am still in the dark w.r.t my claim as explained earlier. What am I going to use if I return the courtesy car today without even knowing when finalization to my claim will be?
