He sends me this:
dude is this a fuking joke?
wheres my gun !!your fuking box was open, no gun,
2 air tanks, a hopper a bag with no zipper a mask, and some fuking barrel plugs.
contact me now !!

I know for a fact I sent everything to him. Either he is trying to screw me over, someone stole this stuff from his house, or something went wrong with shipping.

What am I supposed to do? Will ebay penalize me just because he supposedly did not receive some items?
Paintball gun
