Ignorance at its best.

My dad sadly past away recently and Liberty isn't making this process much easier. We are in the process of submitting info for my late father's RA and Liberty is just not responding to my emails. They have the nerve to state in my last email that should I not respond they would submit the information at hand to the trustees regarding the payout of the RA. Yet the information they would submit is incorrect and incomplete. How can I corporation as big as they are make such comments?
