Dear Kikapu, being the gentleman that you are, why lower yourself to the level of these low lifes .
Perhaps when you have taken the money you would be good enough to donate it to some worthwhile charity, since as you must know it will be blood money you will be getting. At least if you give it to charity you will cut the haram of it.
All the best to you sir, but be careful with whom you are dealing as these crooks cannot be trusted.
