I followed all of the instructions to delete my account a couple of days ago. Now I am receiving unwanted emails ("Take your WordPress.com site to the next level!").
There is no simple link on the e-mail to unsubscribe, so I'm forced to log back into the account that I was assured was deleted two days ago, in order to change e-mail notifications.
Your links are awful. I go 'round and 'round and am unable to change my e-mail notifications. Simply ridiculous. You should not be sending emails to accounts that no longer exist, and I should not be allowed to log into your site with a non-existent/deleted account.
