Seriously unhappy customer

Honestly I am so sick and tired of fighting with these people.This is a family brand that is the most trusted in so many people's lives. Outsurance keeps on adjusting my premium. This is the second time they are trying to take more money from me. I recently claimed for an accident which wasn't at all my fault.They are siting in the new contract factors such as premium non-payments and improvements in risk factors. I have never missed one payment and an improvement in risk factors will not lead to an increase in payments.non the less I am so flipping upset I feel as if I honestly want to take out my insurance elsewhere. Flipping pathetic man
