Cooperators Home Insurance Reviews

I don't know what to think. I have had a farm policy with Co-Operators for years with no claims, or changes. I renewed my policy for 2021 and noticed it had a 20% increase with no explanation. I can find nothing online to support this, most sites suggest 2-3% as to be expected. I wonder if the rate increase was supposed to be calculated at 1.02 % and the girl made an error of 1.20 %. Easy mistake, but her dad owns the brokerage and, well, I'm at a loss as to find the answer. Yes, I will be looking around. If I find what I expect to, I will be taking multiple policies with me.
