No feedback!

My vehicle was involved in an accident on the 31st of May with a vehicle that is insured with Outsurance. I then contacted Outsurance Legal department to lodge a 3rd party claim. I sent through all the documentation that they required. That same week an investigator came to interview me, he was here on Friday June 5. I was supposed to receive a sms with my claim handler's name within 48 hours but that didn't happen. I called and got the name myself. Since then, I have been constantly calling this guy for feedback and he hasn't given me any tangible feedback, just that he is busy validating my claim and will get back to me. On the email from Legal they said they will only consider reasonable car fire if one can produce evidence that they use the car for business, which I do, and I did, but I was told they do not give courtesy cars to third parties. This is now the 3rd week and I still don't have anything from Outsurance. My quote and photos have not been validated, as is stated on the mail from Legal. I am just lost with no clue as to what direction my claim is going. I am not sure if this is because I am not their client or this is how Outsurance does business.
