Hello Ashish:
There does not appear to be anything you can do. Running it from the Wolfram|Alpha search bar wanted me to log into both Wolfram|Alpha and Facebook...to no avail. I also tried these:
WolframAlpha["facebook report"]
SocialMediaData["Facebook", "Friends"]
SocialMediaData["Twitter", "Followers"]
It looks like this function (introduced in V9) is no longer available.
You could report it to the support group (I am sure they already know).
