No feedback on status of claim

I was in a car accident on the 22nd of May and I have had NO feedback on the damage of my car from Santam. They keep referring me to the assessor (who does not answer his phone). I got hold of the panelbeaters by myself and received a quote from them - but Santam keeps telling me they know nothing. It's been more than a week! I have a rental car for 30 days - after that I will be without transport if my car has not been fixed or written off. Santam hasn't contacted me ONCE to tell me what the status of my claim is - I have to nag them to make something happen. This is unacceptable.
