It's the official number on their website, you can't connect to any officer through that number. I even missed the call at first and I tried to call them back but it was an automated answer, but thank God they called back.can we have the number they used to call u and if we may know the exact question they asked u regarding Facebook since we’re all in the same boat so I can prepare Incase they call me on Monday
And regarding my Facebook account, she was asking me if I've travelled to the US before and I said no. So I asked why she asked me that, and she said based on what she has seen on my checked in places on Facebook and someone commented that did I just returned from the US. So I told her I've never ever been to the US but she can contact the US embassy to confirm if she doubt it. Then she said no she just wanted to know because of what she saw on my page.
So I think you guys should be very careful with places you check in on social media esp facebook. It can ruin your application. Thank you
