I assume you ordered it directly from them, and being they are not responding, you have ample grounds to open a PP dispute with them. I found it fairly easy to go thru the PP website screens. I can't recall the exact verbiage they use, but you basically open up a 2 way message conversation with the seller under control and audit by PP, but PP does not get involved. If they fail to respond at all to the PP opened conversation, you win automatically.
Believe me, PP is not in business to lose money, so if enough of these disputes are opened where HaikeLite doesn't respond, or gets to a PP ruling against them, PP will drop them like a hot potato, and I would think HaikeLite wouldn't want that.
If you want to play, gotta play by the rules - hope they don't learn the hard way.
Ohh - bout the lanyard, paracord, string, shoe lace, or whatever you want to call it, it's pretty sad to see it go from a really nice fancy knot, practical lanyard to a simple straight cut piece, or nothing at all. To be fair, on their website it has nothing at all I could find about a lanyard. On BangGood, it does spec a lanyard included, and I'd say a lanyard is not a piece of rope.
I never cared for a product listing where it doesn't include a "what's in the box" list.
