Some Things to note:
When scheduling an appointment, a credit card will hold your time but will not be charged until your scheduled appointment.
If you need to cancel before the appointment, it is vital that you give 48 hours advance notice. For example, if an appointment is scheduled for 3:00 pm on a Tuesday, notice must be provided by 3:00 pm on Sunday at the absolute latest. You may cancel your appointment via text, phone, or email.
