Family ghosted me - home health what do I do?

Hi everyone, looking for some advice on what to do. I recently went to a home last week for a session (I do home health) and the family was not home and not reachable. I have still not heard back over a week later and have another session scheduled for this weekend. Our company encourages confirmation from families before hand that they can proceed with the session but some families are terrible at responding and I’ll often show up anyway. So, do I go to their home again and if not charge a full fee, do I email and cancel since I haven’t heard back from them? Do I charge a full fee, half fee or wave it if I do choose to cancel? The company I work for has it up to my discretion how I want to bill but I’m just looking for advice on how others would proceed. I want to be fair but also want to be firm that I don’t appreciate my time being wasted.
