It would be nice if the appointment emails to the employee would only arrive at the stage when the reservation is certain, and not unconfirmed, and then immediately after that the message that the appointment has been canceled.
The email will soon be filled with messages.
One of our authors received 11 messages about a reservation/cancellation/reservation from the same customer.
Especially when the reservation is less than 24h this time cancellation can bring a nasty problem that we call the customer to put the bill back because aka canceled less than 24h before the time.
