My account has been changed and all my saved game data is gone !

So when i went on Battlefront 2 all my 80 hrs game play had dissipered after checking on all other installed EA games it was the same on all of them.

After further inspection it seemed that my account has ether been hacked or for some reason my user name had changed and all my saved game data from all games was gone. 

If anyone can help i would appriciate it, untill this issue is resolved i will not be playing or buying anymore games from EA. 

Cheers
