Tell PotCO the account name, your beta Pirate's name, your beta Pirate's guild name, and a couple of your beta Pirate's friends names. If you know all that, it's impossible for you to be lying. So, if PotCO had common sense (which, currently, it seems they don't, but you can give it a shot), they should either give you a beta key or give you your pirate and account back.
