He wasn't supposed to switch you to a more expensive policy. You have a dodgy broker.
Non of that is your fault and the insurance would still claim the money back from the party that was at fault.
How much you paid vs how much you can claim is irrelevant, insurance is a group fund/scheme. Everyone' premiums contribute towards covering the damage of those less fortunate.
I think this is what's at the heart of my question. I also understood this to be "how insurance works", but from the responses here and my experience this doesn't seem to be the case. It seems as if each individual is seen as profit opportunity with premiums being increased once the total amount collected in lower than the total amount paid out.
Insurance is more about risk, than it is about fault. When it comes to car insurance fault is just another factor that adds to the risk, just like living in a dodgy post code also adds to your risk profile, regardless of how careful you are.
My counter argument is then that the risk should be spread and not each individual treated as a profit centre. The bicycle guy who hit me had no loss, the insurance has no loss and I have an increased premium.
I didn't think that this is how insurance works.
