account restore my account

Hello, I encountered an issue with my meta account while in developer mode. I came across your blog post that suggested deleting the meta account and creating a new one with my Facebook account. However, after deleting my meta account, I am unable to log in with my Facebook account, and I am now locked out of my account. Can you assist me with this matter?

my name is Nir Zigdon
And my email is Zigdonnir gmail.com
thanks
