i had this same problem with a wallet i bought from bluefly
It was sent dhl and they left it on my stoop
i am not sure where you live but i live in brooklyn ny and there are people around my stoop all the time, i dont have a porch i have a stoop
the menu guys come up the stoop like 40 times a day, mail men, flyer ppl etc
and so i was waiting and waiting for my package, then i had to go out
then the next day i was waiting and waiting and went to track it and it said left on stoop
WELL if it was left there it was gone by the time i got home so blah blah long story short i had to wait like weeks and weeks for dhl and bluefly to investigate and see if they could locate the package (like did the guys not deliver it or something?)
and then like weeks later finally bluefly had to resend it and with a signature required and DHL of course somehow had to take care of it cause it was their fault for leaving it
without a signature means the driver CAN leave it at his own discretion, but HELLO no one in their right mind thinks its a good idea to leave a package on a stoop where people are 15 steps from the front door all day every day UGH
im so sorry!
it was such a pain in the ass working this out BUT it did work out and i had my item resent so dont fret i think that if for some reason somone took it you will get a replacement and of course you wont be out any $ good luck keep us posted
