A family member fell for this while trying to recover their hacked fb account. I was around and caught wind of the call and some of the absurd steps (absurd to me, anyways) they were proposing and pulled the plug on the "support" call. The phone number was in what seemed to be a cached result of a bad search or something. '"Call us at xxx-xxxx..." not found' is what I saw. (Finding a real support number is either difficult or impossible, which makes this a good trap)
