I like the fact that youh played along woth the scammer's game. Your aunt's husband trusted a wrong person, his trust was because he had been speaking with the scammer for long. It's a normal way for scammers to have a very long chat with targets till he/she earns the target's trust and introduce his
/her own offer which is the real reason why they have been chatting with the target.

That's just one out of many crazy experiences from hackers and scammers.
