Santam giving Bad Service

Santam claim number *** My wife was involved in a car accident on the 9th of February and the vehicle was towed and assessed by the panelbeaters. On the 12th of Feb we received a car hire. Santam and its approval processes took more than 2 weeks to approve and the panel beaters are saying the parts will take at least 21 days to arrive into SA. Only on the 26th of February did Santam approve the claim which was 2 weeks later. I asked the gentleman who was assisting me about this delay and its effect on my car rental and he just said we will cross that bridge when we get there. Now the same gentleman is telling me now they wont extend the car hire even tough its their fault and their service providers. This is ridiculous!! I am cancelling Santam and i gave the gentleman notice. If they cannot assist me when it matters then whats the use of having them.
