It looks like you own tommysimpson.wordpress.com with a custom domain, papatomsinquiry.com that expires on September 29, 2014.
Is your goal to move your site to a different hosting provider and use papatomsinquiry.com as the domain there? If so, you have two options.
1) You can point the domain to your new hosting and keep it registered here. You will need to keep tommysimpson.wordpress.com active so you can manage the domain, but you can set the site itself to be private so no one can see it.
2) You can transfer the domain papatomsinquiry.com to a new registrar and then, once that has been completed, you can delete your WordPress.com site. (Please note that we are currently experiencing a temporary glitch with our transfer process and are working with our domain registrar partner to sort that out.)
If you have no interest in continuing to use papatomsinquiry.com here or elsewhere, I can cancel the domain for you and remove it from your site, which will free you to delete tommysimpson.wordpress.com. Please note that once a domain has been cancelled, it may not be available to register again later.
