If he has access to your Battlelog, then it means that he also has access to your whole Origin account. In that case, you need to contact an EA Advisor via live chat or phone to report this. For extra security, I would recommend doing it from a separate, non-hacked account. Before you contact the Advisor prepare some information:
A serial number from one of your games (if possible), it's the easiest identifier that can be used to locate an account. If you do not have a serial number available your Gamertag, PSN ID, or Character Names from online games will have to suffice.
The email address you would like to be contacted at
The original email address for your compromised account
Your actual date of birth
The date of birth used to set up your account
