The second question refers to why the offer is only valid "next few hours", and how it is possible to unlock (mediate in unlocking the account) without knowing any information about that account owner?
Or maybe Boombl4 is probably trying to use the 72 hour time to his own advantage and fool OP into believing that he did something to unlock OP's account. I have seen cases when People's accounts get suspended and then get unlocked after 72 hours after investigations.
That's why he's saying offer is only Valid in the next few hours... because he knows that time is running out and OP's account could be unlocked anytime, if all goes well
