Hafeez, can you read and understand the email as it was written? It says, you cannot have a facebook account. It is a final decision by facebook. We are NOT facebook.
It is not the end of the world. It will be ok if you do not have a favebook account. It is not like an organization is going around the world asking individuals for their proof of facebook, or you get thrown in jail!
I promise you, you will survive!
