My feelings on the matter are irrelevant, I am simply trying to respond to your post as best I can. The 4 day window in which a buyer cannot cancel the order is there to protect the vendor from having the very issue you have now had and I will pass on your comments regarding this not being included in the sellers guide to DPR. I should also correct you, auto finalize is 17 days from the date the order is marked in transit not 19. This is also not a security leak. I am sorry this happened to you and I can appreciate your feelings on the matter, my advice would be to raise your concerns with SR support and explain what happened to them also.
