Let me get this straight, you want a knife that BladeHQ has. It is their knife. You paid for it with an international CC. BladeHQ flagged as possible fraudulent card. So now they need to protect themselves and their knife (which they still own). So you are asked to reply within 24 hrs but cant? Remember, this is their knife, which you want. That means you have to do your due diligence.
Were you expecting them to ship a knife to you with the “hope” that they wouldnt get screwed? This whole thing makes no sense.
Kudos to you
@BladeHQ for even responding to this post.
