Disappointing claims experience

My business is insured with Santam. I had a car accident at the beginning of April, with another Santam client. I am claiming through the Santam third party department as the accident was the fault of the other party. It's been almost two months since this accident and my car hasn't even been assessed. When I asked for an update I'm told an external assessor has been appointed, I have sent in quotes for my damages from three different panelbeaters ages ago. I then find out today that the external assessor was last asked for an update a week ago, Santam is not staying on top of asking them to hurry up. I am seriously reconsidering having my business insured with Santam if this is the way third parties are treated
