Generally, users can log into their accounts or refer to the confirmation email received when they scheduled the appointment. This information may contain necessary details on how to proceed with cancelation or rescheduling. It is essential to review these policies carefully, as there may be time limits or specific requirements to follow. If there are any uncertainties, users are encouraged to check the current web page for further details or potential contact information for assistance regarding their appointments.
