How should I handle this?

Hello! So I had a booking for a drop in from 12/25– 1/2 and my client just let me know they will be home today, so I’m not needed the next two days. I’m pretty new to sitting and I’m not sure how to charge for this, and also how should I handle this on Rover so it doesn’t look like I just didn’t go the last two days of this sit? Any advice is appreciated!
