My client inadvertently booked a recurring weekly schedule. They are back from their trip and no longer need me to stop by. I cancelled the booking but it still shows that I am to stop by this week. How do I stop that?

My client needed me for a 2-week period. When they booked the inadvertently set up a weekly recurring schedule. They are back from their trip and no longer need me to stop by. I canceled the booking yet it still shows me scheduled to drop in several times this week. How do I stop it so it doesn't come up as a no-show?
