I can not log in when using the website.

I wanted to log in to minecraft.net in order to change my username, however when I go to that site, it doesn't even give me the option to log in. [as seen in the first screenshot]

 

I've tried evading that problem by directly going to minecraft.net/en-us/profile but it puts me in a loading screen that seems to be bugged, judging by the font, and just never finishes loading. [as seen in the second screenshot]

 

I was wondering what I could do to fix this problem. I've tried changing my browser, I've tried almost anything. This problem has been present for two days straight. If it's an unsolvable issue, i want to request a username change, as a hacker got into my account and changed my username last month.

 

Thank you for your time, I'm awaiting a response.
