Who I have the same questioned this topic

I have recently (48 hours) been trying to start a new line on my acct and also add a new iPhone to that line. When I get to the "Confirm your Details" page of the process, the page just continues loading, never ending and doesn't allow you to click on anything or advance to the next step in the checkout process. Is there a common occurrence? I've checked roughly 10-15 different websites and they all are working well. My internet is working perfectly as well. I am really starting to lose my mind. I just want to buy a phone and a new line and the Website just absolutely refuses to let me accomplish this!! Please help!!
