Outsurance Increase premium by 45%

I am extremely dissatisfied. Outsurance says one thing in their adverts and what they put out there but once you become their client then they speak a different language. I am dissatisfied because Outsurance have increased my premium from R1652 to R2550 which works out to a 45% increase. I have called in to query this and their response was that I had two claim incidents. I questioned them to ask why do I have insurance? it is to be able to claim. Meaning I pay monthly premiums that covers me for the risk of claiming and now I must also pay because I claimed. That means I am paying double the risk which they should be taking but shifting to their clients. Now I am not saying that there shouldn't be an increase because everything goes up because of inflation but 45%? No one in South Africa that I know of gets an increase in their salary of 45%. Inflation is 8% and their increase is far beyond that. I spoke to senior advisors and a senior manager which was unable to assist as I was trying to request that the increase be brought down to 15% of which they were not prepared to meet. I never missed a premium, nor was it ever late for the past 5years that I was insured with Outsurance. Even this did not help in negotiating the premium down to 15% increase. I would hate to move but Outsurance is making it impossible to have cover with them. We are a family that sticks together and If I should move then my father, that has been with Outsurance for +-20years, will move as well as my sisters. This I have also mentioned to the manager of which the call was recorded. This is by far the worst I have ever been treated by an insurer and surely hope that someone at Outsurance is able to assist to review our policy.
