Origin account

hello,

I recently got my hands on a ps4 and bf4. And i accidently did not use the same origin account in the startup menu. Now i have 2 accounts. 1 one them is my account from my ps3 with al my veteran stats and the othe is mistake

Now my question is: Is it possible to delete those accounts and link my failed account stats to my veteran account? Because for certain items ingame you have to be veteran and i love to unlock them. I also noticed that i have another account, but with no log in.

1 final thing: When i was in the game and went to the chat by pressing on the ps4 menu butten. My controller ingame didnt respond anymore. The game did not freeze, but i couldnt use my controls. This happens several times. 

I am sorry for my simple english. I hope you understand what i wrote.

thank you
