|1.||Will it better for me to call for an appointment?|
Feel free to call if you cannot use the online appointment function. If it's off hours, do use the online appointment function so that you can get in sooner.
|2.||How easy is it for me to request an appointment online?|
Your appointment request is done in real time. This means that when you request a slot of time for appointment, that slot is booked immediately. However, it doesn't mean that you are guaranteed to be scheduled for that time slot. Wait for a confirmation.
