Facebook confirmation code won't work

Hello,
I LOST access to my facebook account, I logged off just to switch phones, when I tried to log back on it says my password is wrong. No big deal, Right? So they send me a confirmation code via text, but the code doesn't work. And each time I request a new code, they only email me or text me the same code, over and over, that still doesn't work. If anyone could let me know how I could possibly contact fb or if I'm doing anything wrong, please let me know bc this is driving me nuts! Thank you!
