5 different excess amounts quoted telephonically, no written communication

The service I have received from Santam regarding the communication and finalisation of the repairs of my vehicle has been absolutely shocking. An accident and the inconvenience it causes are already traumatic enough, I didn't expect my insurer to add to the stress. The Digital Assesor handling my case has quoted me 5 different excess amounts in the space of 2 weeks and to date I have no written confirmation or quote from Santam unpacking the tripled excess amount that I now need to pay. The garage has been hounding me everyday to pay the excess upfront before they can start repairs on my vehicle, but ZERO communication from my insurance who I have a contract with and pay my monthly premiums to. I would strongly advise anyone against taking up car insurance with Santam based on inconvenient and unpleasant experience.
