The worst customer service I've ever experienced in my entire life.
Standard hold time on a call is 2 hours to get onto offshore reps who have absolutely no understanding of the NBN. They can send you default emails with instructions to set up your modem, in most cases any information they do provide will be inaccurate as they're clearly going off some basic training materials.
I am currently on hold for 3 hours because they gave NBN Co incorrect contact details for me and I have no idea when my rep is booked for, Arctel portal doesn't bother recording anything on your bookings and they don't even have an online chat.
Don't do it. It's not worth it.
