Why cant I disactivate my stupid facebook account?

[Victoria]

I keep on trying to disactivate it but its not freaking working!
I hate facebook I am so done with all the drama and people excluding me.
So this is what I did
1) I pressed on account settings
2) menu
3) Clicked Security
4) And finally I clicked 'disactivate facebook account'
I did this, and soon after this page came up asking me for my reason of leaving facebook, I gave them the reason thats its temporary and ill be back. I confirmed my password, as they told me to, and after this pop up comes and it says "Please choose a reason its mantorory" or something like that! I keep pressing every reason possible IT STILL KEEPS SAYING I DIDNT CHOOSE A REASON!?! please help I hate facebook so muchhh help me?
