Disgusting premium increase.

I have been insured with Dial Direct for a little over a year. After the policy review my insurance premium increased by R500. This kind of increase is beyond ludicrous, its actually disgusting. I don't see how this can be justified as none of my details has changed, I am working from home and drive less than 500km a month. After contacting the Dial Direct call centre the agent contacted the rates department who offered to decrease my premiums by R300. That's still a R200 increase. Even with the offered decrease, the premium is still more expensive than what I have received elsewhere. Needless to say, I have cancelled the policy and will be moving over to a different insurer.
