Isnt facebook banned in Pakistan?
For one…However you’ve gotten to use it was just amazing.
Secondly, if you are hacked, contacting the FB customer service is the only way to go if you dont know your way around it.
Run a Antivirus/CCleaner and you should be able to find a Keylogger file in your win32 folder. That simply means that someone can hack any of your account. Because you are getting hacked rapidly.
Either use proxy.
Or
Format your computer and reinstall it.
