1) Gift card = scam. Always, 100% of the time. No government agency and no legitimate company will ask for payment via gift cards, ever. My in-laws nearly got scammed by "Apple support" calling to say their router had been hacked and was being used for illegal activity and that they needed to pay using iTunes gift cards to have "Apple support" "clean out their router".
2) Nothing is immediately urgent. Unless someone is dying in front of you, the problem can be solved later. Banks, government bureaucracies, lawsuits, etc all work via snail mail and lawyers and paperwork, not by calling you up and telling you you're going to jail and are going to lose all your money unless you do something immediately.
