Battlefield battlelog. How do i delete soldiers from the profile?

I am trying to delete 2 accounts that i made. Kind of  embarrassingly, i accidently wrote the names wrong and i want to get rid of them. I am speaking of the 2 realnoob soldiers. Link to my battlelog account http://battlelog.battlefield.com/bf3/user/vVv_Sn1peZ/ . But the most annoying part is that i don't remember the answer to the security question in my ea origin account. I must have typed something random to it when it first asked the security question. How do i delete them away?? Btw I am playing on ps3. Help would be much appreciated!
