lmao i got a good idea
first put a pice of paper under the door of their house saying
"im coming"
then they will freak out
the next day you dotn get your stuff
put a pice of paper on their window saying
"almost here"
then if they dont send it back take a picture of a knife in your kitchen, then put it in his room, through the open window
then one night go up tohis window and use a heavily distorted microphone or whatever, and say "im heeerrrreeee"
then "return the stolen, or its over for you" and vigirously continue knocking on his window, until he gets up turns on the computer and you get your stuff,
and if it doesnt work, just hack him
