Locked out of WP and need to delete blog and domain

Hi all,

I can’t find a direct way to contact WP so apologies if I’m in the wrong place.

http://www.ascension-audioworks.com is the address of my old business, the login email account has been deleted and I have no idea of the password. I basically want to delete the whole blog and get rid of the domain so that google etc can’t see it when it updates next.

Please can someone help with getting in touch with someone who can do this for me?

Any help appreciated

Charlie
