How do I delete my account?

How do I delete my whole entire Shapeways account?

Look at the bottom option.

Of course, the pertinent question would be... Why?

I want to delete an account. The reason is because I created my first and then later tried to login with facebook and ended up with another (which I do not need).
I want to delete the latter. I then want to change from being ANIMEMI to the username of the account I deleted.
