Discovery Insure - Increasing Premiums

I am a professional working for a listed company and I would like to raise some intense frustration and shocking service with Discovery Insure. I have been with Discovery Insure for almost 24 months now and been a the main member of Discovery Health for going on 6 years. I just took ownership of a new vehicle and traded my old vehicle in (on which I had one small claim). I called Discovery to change the vehicle and gave them ALL the truthful information as usual. They quoted me R1300 for the new vehicle of which I was quite content with. Happy with the service a day later I approached Discovery to add my household and water craft to my policy. My vehicle premium jumped to R1700. I queried this and it was explained to me that the previous consultant did not stipulate my claims history (this will be clear in the recording that I did stipulate it quite clearly), hence the increase. I have now (14 days later), after challenging the previous quote had an email to say that it is my anniversary with discovery and my premium is now in excess of R2000. I am growing as a professional and will have more assets to offer discovery however the call center were quite happy for me to terminate!
