Sounds like you might have been hacked. While Answer HQ is only a peer to peer help site, and not the official EA Customer Service site, and we cannot actually alter anything, we can give you advice on what to do if a user has issues like yours.

If you get hacked the first thing in my opinion you should do is to reset your secret question. If you need to reset your security question go here and follow the provided instructions:

After resetting your security question you should follow these instructions which tell you what to do if you've been hacked: http://help.ea.com/en/article/i-think-somebody-hacked-my-origin-account-what-can-i-do-now/

Then you should get a hold of an in game Game Advisor here: http://help.ea.com/en/contact-us/new/
