Unfair and Discrimantory Treatment

I am currently a client of Iwyze for over a year, I lodged my first claim on the 14/12/15 and got a raw deal. My claim was kept on hold and the reason was that they are validating my other claims/looses with my previous insurances (surely this should have been done during inception). Finally the claim was approved on the 31/12/15 with conditions that my policy will be reviewed by the underwriters and premium will increase as they view me as a high risk client based on incorrect information they claim to have received from my previous insurance. According to Iwyze, I had 8 claims with my previous insurance and when this was verified there were 4 and out of the 4 claims 3 of them were a third party's fault. I also discovered that a claim of R10400 was inflated to R104000.00. Desiree came back to me informing me that her managers have made a ruling that my policy will not change and I have proof (email). Later I received a call from a different consultant of Iwyze informing me that my policy will be cancelled in the next 30 days. I need to remain the client of Iwyze without interfering with my premium (I feel discriminated that I am being refused insurance because I claimed)
