Nedbank Car insurance (Iwyse old mutual) will not pay my for my claim after my car was written off!!

I met with an accident on the 9/9/17. It was really traumatic and I was hospitalized for 6 Days. I submitted a claim to Nedbank on the same day at 8am. Today (7/12/17) I received a message stating that I need to hand my courtesy vehicle in by 5pm. NO ONE CALLED FROM NEDBANK TO GIVE ME AN OUTCOME! I called the call Centre and they told me they can not disclose the outcome I need to wait for a guy by the name of Delano (Investigator) to contact me. An hour later Delano called me and said that my claim has been rejected due to me not informing them about an “accident” that I’ve had with my previous insurer (outsurance) this incident was a minor incident and I DID NOT CLAIM FROM OUTSURANCE!! Please can you help bring justice to these **********! I did my background check and as long as I did not claim on my vehicle I’m in the clear! I did not even consider the incident an accident therefore I did not disclose, I did not see it fit knowing I did not claim. I’m with Nedbank from 31/7/17 and therefore I feel they looking for every excuse NOT TO PAY! When we take insurance to expect the insurer to be there in times of need. The incident with Outsurance had NOTHING TO DO WITH MY CAR! My car was not damaged except for a scratch in which I got fixed privately!! No I’m paying MFC for a vehicle that I don’t own!! Further more they want to cancel my policy from the time I took it out. Return a written off vehicle to me. And return all my premiums. They will take out the vehicle hire which I paid for!!!
