You don't get a "refund" from your life insurance policy for not dying.
You might have some cash value that has built up over time inside your life insurance policy you can take out as a loan, but you'll have to call the life insurance company and ask if there is any cash value inside your policy.
Term life insurance does not build cash value, but permanent life insurance plans may have some cash value inside the policy.
So, it depends on what type of life insurance plan you have, an how long you have owned the policy and paid premiums. The longer you have paid premiums on a permanent life insurance policy, the more money there may be available.
