Username changing not responding

Hello Mojang. 

I'd like to report a bug where when ever I go to the Minecraft.net page to change my username it doesn't work and just stays frozen un able to click anything but just scroll and close the browser. 

If you wait sometime the page will come up with "Page Unresponsive" saying to close it or wait for it to respond. If I wait for it to respond it doesn't do anything. 

When I type in my name and it comes up with no wait thirty days or username taken, I then clicked the change username. However that just made my tab completely frozen unable to do anything besides from scrolling up and down. 

Please fix this as it's been two months for me now and I still haven't been able to change my Minecraft username.
