Forgot password and email to my account "OneTrueKing"

All i really need to know is the first and last letter of the email address associated with it and I can reset it. I have so many emails and I swore i used a specific email for it but cant find it so far. Im also on the same computer I made the account on and can tell the date the account was made if that helps. ALso I have the account password saved too.
You'll have to email [email protected] to help get this sorted
In response to F0lak
ive emailed them a day after i made this post and i still have not gotten a response. How long am i suppose to wait for?
