Re getting off the awful Facebook, i was wrong, you cannot call them. A phone no. online for doing that belongs to scammers.

You first have to deactivate your Facebook profile. Google how to do that.

To permanently delete Facebook, you have to go onto your profile and then contact the Facebook people. You can still do that after it has been deactivated. I don't know how to do that so you would have to ask around to find out how. I just wanted to say that there is no phone number to contact Facebook about anything, that info was in error.
