I have the exact same issue, my account was hacked and all valuable tradable players were cleared out if my account - only the SBC's i had grinded out remained in the club. 

Went through the account recovery stage with EA for over a month, which was beyond a joke. One email response [per day at the same recurring time of 12:00pm I finally managed to regain access to my account only to find out a few days later that I was completely banned for breaking the T&C's. 

No response to my freshly made case for over a week and a half now. It's staggering to see how much EA make from the game, yet their customer solution department is clearly something that remains underfunded.

Beyond frustrated with this experience and the lack of customer service received.
