best way to get into contact about getting an account that was hacked

so about a couple of weeks ago i was trying to get into battlefield 2042 and when i would play for a bit it would crash and i thought it was something in the files and i verified it through steam because i bought the game on steam. and when i opened the ea launcher i noticed that i was logged out and i tried to log back on but it said to send a code to a random email and i tried to reset my password in another way but nothing. then after i tried for days to try to get it back to at least unlink the account off my steam because i cannot play any other games since my steam is linked with the account.
