How can i change my EA/Origin Account on my ps3 battlelog for bf4

What you can do is link your new PlayStation ID to your Origin account and then remove the old account, or you can create a new Origin ID and have your new PlayStation ID added to it.

Link your Xbox Live gamertag or PlayStation Network ID to Origin like this:

1. Log in to your Origin account
2. Click Friends -> Add a friend in the menu bar
3. The pop-up will give you the option to connect to Facebook, XBOX Live or Playstation Network. Choose your preferred option
4. Fill in your log-in details and follow the steps on screen

If everything went fine, then you should be able to see your Xbox or PSN account listed under Connected Accounts in your account management page (click Account and Privacy in the menu bar).

In order to get a persona unlinked from your account, you will need to contact a support adviser here.

Steps to contact Support are listed in this spoiler:

Spoiler

1) Click on the game you're having trouble with. (If you don't see it, use the search bar)


2) Select the platform you're playing on/are having problems with.


3) Select a topic and list a short description of your problem.


4) Select the way in which you would like to contact EA. (Options may vary depending on the problem you're having, and your location.)


Remember to be kind, respectful, and patient with your Support Adviser. Your problem may not be resolved right then and there, but they will do their best to get it resolved as quickly as possible. Thank you!

its not a New PSN Account  its a new Origin account i would like to link to my PSN account i play on and remove the old origin account

@DeMerciless You can unlink and relink your account via EA support. Remember doing so all stats for all games will be lost.

Thank you it worked :D
