HOW CAN I DELETE AN ACCOUNT?

I made my profile-account at mixcloud BEFORE i joined facebook.
now i was login with my facebook account - and mixcloud made up an new account.
that is not what i wanted.
now, i figuered out, how to connect my first mixcloud account with my facebook account - ok - this works.
but still - this empty new account (with this porilfe picture from facebook) is still there - why?
DJ Friends of mine still get messages about "'xxx' started following you".
you can click it on mixcloud - you can see it on mixcloud - it is still there.
I tried to "closed" it.
But it's still visable.
how can i DELETE this empty new account with the wrong connection to facebook?
why is it so difficult?
once, you made an mistake - you're trapped.
everytime i clicked on mixcloud it was already connected to my new empty account.
Gee-zuz.
