Miway worst insurance company ever

MiWay is one of those insurance companies that has put up my premies each year with very high percentages which is ridiculous. Each year I have to phone them to lower my premiums, which is now not longer acceptable to me. Why do I have to do that, they just ask what they want and this month they increased my premium by R895 a month, a 35‰ increase. Never have I ever seen any other company asks so much. MiWay is the worst company that I ever done business with in 40 years I been with an insurance company.
