Facebook - I cant be frank coz it might not be allowe6

I have had 5 accounts hacked and to this day Facebook has done nothing about it. No my current or what I thought was current and working has a security check. Facebook lite on my mobile worked perfectly but the security pin they want to sent is not mine, so trouble shoot to contact FB, and what do I find? Yes you can get many many options for help all you need to do is log into your account. Honestly.
