Owner is home early but I'm still booked for a drop-in. What to do?

I have been doing twice daily drop-in visits with a cat, which was supposed to end tonight. The owner contacted me saying they are home, but I am still booked for a visit tonight (they haven't cancelled the booking). What am I supposed to do? Will I still get paid the full amount if I don't complete that drop-in or will Rover reduce my pay? Will not completing the booking affect my Rover profile? Should I ask the client to cancel the booking?
