Why is this thread dead and with no good answers? I thought this was a quality forum?

I guess unlike other situations/ideas social engineering cant really be spoon-fed with a a definite answer - the person on the end of the phone will be completely different every time and its a skill to take when you can from the conversation about how the other person works and use that to your advantage.
DNA is tricky if you do have to sign for it, yet if you know what you are doing in that specific situation you can get away with it.
Personally same, I stay away from DNA unless they leave it outside in which case you best believe im getting my money back, its a method that shifts blame to the delivery people in which they can kinda verify reliably, whereas other method of SE Refunding removes all blame from both parties in which makes the claim a lot harder to dispute!

I kinda went on a rant, but I hope I made sense - DNA is exactly what it is, the item did not arrive, when the delivery guy has a form of semi evidence its often a case of your word against his, but with good social engineering you don't want to be in this situation - you need to manipulate it into your favour and thats the struggle with DNA.
