Ridiculous premium Increases - Consumer Exploitation

I have been with Discovery Insure for 5 years. I drive a Ford focus 2015 model with a depreciating value. I have not claimed for more than 2 years. Because I don't drive my car that much anymore. I have been working from home for the past 2 years. Let me tell you, Discovery Insure has increased my insurance premium twice in one year. In January 2022, my premium was going to be increased from R2, 100 to R2, 300. I negotiated that my premium be increased to R2, 200 instead . On the 23rd of December 2021 I received an email stating that my premium will be increased by a further 20% on the 1st of February 2022, which means that I will be paying Discovery Insure R2, 600 for 2022. This amount is ridiculous. It's close to a car installment. My premium has increased by 24% in one year, yet I have not claimed in 2 years, My driving has improved, I have had my driver's license for more than 5 years, I don't drive the car that much because I am working from home and the value of the car is depreciating. It's unfair. If possible, please refrain from joining Discovery insure. Discovery Insure is not treating customers fairly and is exploiting customers.
