How do I TOTALLY DELETE my Facebook account?

[kjv_gods_word]

I created a temporary Facebook acount just to see what it's all about, but I don't want to use it. I keep getting tons of invitations and there are posts in my accounts from both people I know and don't know - though I NEVER accepted any friends invitations. And now there are sexually themed posts being made. I tried to delete my account but the only thing I see is an option to "deactivate" the account. I tried that, but I keep getting emails saying that my account has been reactivated and peole are still trying to "friend" me.

I want NOTHING TO DO with Facebook. I want my account totally DELETED. I can't find any link to contact Facebook for help. CAN SOMEONE PLEASE HELP ME?
