Hi Piotr,

According to the tracking information, AG680783420CN was delivered on April 6. 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 China Post to do a formal trace investigation. 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.
