FB Login Problems-repeated "Not logged in Please login to cont."

I can no longer login to Facebook on any computer. I deactivated my account under the impression from FB instructions that it would reactivate in 7 days. I'm totally confounded as to whether it actually ever deactivated. I was told via email it had yet it never ceased working on my phone. Now when I try to enter FB on any computer it repeatedly tells me "Not logged in, Please login to continue". However, when I select [login] from this warning dialogue box it first puts up the same dialogue box a few times, and then it opens a login window...endless loop. The only help options I find on FB require me to be logged in, hence I cannot use their help. There are no phone numbers for support (I'm old I expect this for any business) so I'm lost as to what to do. I know googling and use it extensively but cannot find a solution that works. Please help.
