Owners: leave email blank. Managers: sign in with your staff email.
This refunds the customer in Stripe, removes the calendar event, and sends them a cancellation email.
Pick a new date and time. The customer's payment and event link stay intact — we move the existing calendar event rather than refunding and rebooking.
Fix a typo in the customer's name, email, or phone. Nothing is sent automatically — use "Resend confirmation" afterwards if they should get the email at the corrected address.
