Is anybody else having trouble ordering on JB Hi-FI? I get to the "customer and shipping information" page and enter my information, but the "proceed to payment" button isn't highlighted to allow me to go to pay for my order. It says that my phone number is invalid. I've entered my number both with and without the preceding "1" for the United States, but it still says it's invalid. I've tried on both my phone and laptop, but it's the same. Any help would be appreciated. Thank you.
