Stolen Account

I have account problem, As in the title. My account seems to have been stolen by someone, initially I deleted the FC Mobile game and then reinstalled it, but for some reason I ended up creating a new account, while my login method was via the same EA ID, after I checked the account it turned out to have been stolen by someone, as evidenced by the formation that should have been 442 being 433 and the dembele I had in that formation was replaced by Vini Jr. 

And the perpetrator also seems to have hacked my Gmail account, as evidenced by my cellphone being factory reset. 

I don't have enough proof because my phone was reset, but I still remember what the first Gmail account looked like when I created the EA ID account and the FC Mobile account. 

Thank you to those who have given suggestions or methods that might be effective, I have also reported this to the ea.com website, but I just want to see what your answers are.
