Excessive premium increase and failure to claim from 3rd party

My premium just went up by Almost R700! I called Miway and the consultant told me that it’s the annual review of my policy. I told the consultant that I simply cannot afford to pay more than a R1000. Also, MiWay has failed to claim back my excess amount due from the third party even though the third party was under the influence of narcotic substances and alcohol without a driver’s license. I was still liable for excess and it has still not been paid back to me. After all the inconvenience caused, MiWay still is the audacity to increase my premium from R960 to R1660. My excess has also went up ridiculously. This is **************** by MiWay and after being such a loyal client, I am disgusted and nobody has called me back to assist.
