I am writing to express my frustration and dissatisfaction with the handling of my car insurance claim and the significant increase in my premium. A year ago, my car was hit by a drunk driver who did not have a license. Despite the accident being entirely the other driver's fault, I have been paying almost £300 per month in premiums. Over the past year, Aviva has been unable to obtain the necessary details from the other driver to pursue them and reimburse my excess. As my policy is now up for renewal, I was shocked to see the proposed annual premium of £4399.67. This is an unreasonable increase, especially given that I have already been paying a substantial amount for an accident that was not my fault. I expected better from a company that I have trusted with my car insurance for some time now.
