Attempt to serve child’s father for child support but has yet to be served.

My father’s child was attempted to be served child support but he was no longer at the address he was staying at. I’m aware he moved to an apartment complex but not sure where.

He has been entirely absent since my daughter was 3 weeks. She is now going on 7 months. A rep for child support informed me that our hearing date was scheduled so far out in August since he has not been served. However there has been so updates since they attempted to serve him in December. Is there anything I can do?
