Somebody signed up for Facebook using my email. Disabling does not work [closed]

I do not have a Facebook account and I do not wish to sign up for one.

At the end of January, I started getting Arabic Facebook mails. Apparently somebody had signed up to Facebook using my Gmail address (with an additional ‘.’; think fo.o@bar.com rather than foo@bar.com, which still ends up being directed to me.)

At first I just ignored it because I assumed it was a phishing attempt, but it soon became clear that the mails were actually from Facebook.

I soon found the links at the bottom of the mails that would allow me to ‘disavow contact‘, prompting me to an English Facebook page asking me if I wanted to disable the account.

Didn’t sign up for Facebook with this account?

Someone recently tried to sign up for Facebook using [fo.o@bar.com]. If that wasn’t you, you can disable the account.

But whenever I try to do this, it says

Sorry, something went wrong.

We’re working on getting this fixed as soon as we can.

It has been a couple of weeks and it still does not work.

What can I do? I do not merely want to block mails from Facebook, I want this account not to be tied to my email address.
