Hi Peter van den Hooven,

If you don't get it, you need to contact the seller to reflect the problem and get a solution as soon as possible. Only the seller can require the courier to do a formal trace investigation about where it delivered and who signed for it. If the seller doesn't reply you, try to contact your bank or visa company to ask for a charge back. Or, open a dispute from the platform you buy it to get refund in time.
