Hi Kaylon, kaylonkirk.com used to be registered with another registrar, and it looks like it expired a few months ago and is available for registration again. (I usually check http://whois.domaintools.com/kaylonkirk.com to find out a domain's publicly available registration info.)
What you had previously purchased from us is a Domain Mapping upgrade, which only works if you own the domain name and have the nameservers set up to point to WordPress.com.
I removed that upgrade and gave you some credits instead. You can re-register your domain name via this page: https://kaylonkirk.wordpress.com/wp-admin/paid-upgrades.php?page=domains
I hope this helps, let me know if you have any more questions!
