Your mobile number was removed from your account

As I posted earlier, am being stalked by an out-of-town hacker.
Well, the fun goes on.
I created a new Facebook account today, and set up 2-factor authentication, so a code would go to my cell phone and avoid being hacked again.
About halfway into the day, I got this message: "Your mobile number was removed from your account and can no longer be used for 2-factor authentication".

So now I am basically wide open for another hack attack.
WTF?

I tried to go back in and turn 2-factor back ON. And there's only a button now that says "TEXT MESSAGE SMS: Use text messages (SMS) to receive verification codes. For your protection, phone numbers used for two-factor authentication can't be used to reset your password when two-factor authentication is on."

But when I click this button, it says: "2 Factor Authentication: Enter Phone Number".

In other words, somehow 2 Factor Authentication has been disabled on my Facebook account.

I tried going into the Facebook Community Help page and posted that I was being hacked by a stalker, and explained the situation.
The moment I clicked "Post", I got a message:

"You're temporarily restricted from posting in the Help Community until 16 August at 15:46"

Okay, so let's review:
1. Hacked by hacker
2. 2 Factor Authentication protection by phone removed itself, and only leave the option for a SMS text message
3. The SMS text message button, opens a window requiring a phone number, which is disabled
4. The help desk has been disabled, so I can't report the problem.

Nice.
If this is all a hacker, I have to wonder how they put bread on the table when they have all day to harass me.
