How do I handle a retainer client who consistently underutilizes my hours?

It is possible to have a retainer like that. That's why it is better for a freelancer to be firm in his doing. Make sure that you are not allowing that. Ensure that you tell them how important your works are for them to understand better. There is a need to tell them how important your time is, and they should please express their loyalty by using your time and resources better. What do you think?
