Hi there,
I do see that this information was changed on your blog, followed by mass deletions and deletion of the blog. With the proper account verification information, we should be able to help you.
I'm sorry to hear you have lost access to your WordPress.com account.
We will accept one of the following alternative account verification options:
* The API key associated with the account. Please see this link for more information on API keys:
http://en.support.wordpress.com/api-keys/
* A Paypal Transaction ID for any upgrades purchased for the account. Keep in mind that since PayPal is our sole payment processor behind-the-scenes, this transaction ID was generated even if you paid via credit card or another method:

* The titles of any unpublished draft posts or pages you may have
If none of this information is available, let me know.
Please let me know if you have any other questions.
