It's possible that the only "crime" here is that somebody has a name that is similar to yours, with some proverbial wires getting crossed at the insurance company.

You don't have any basis to make a claim against the insurance company for their issuing an insurance policy to somebody other than you, even if they have the same first and last name as you. Or, for that matter, even if the policy was opened by somebody claiming to be you. Even before noting that you suffered no harm, they did nothing wrong in issuing the policy.
