17TRACK Shows My $160 Package as Delivered but I Received Nothing

My shipment with tracking number AMTS000123806FS, which I have been tracking via 17TRACK, is listed as "delivered" in the system, but no delivery was ever made to me. I received no phone calls, nor did any courier come to my door. I have been waiting since April 2, 2026, for this product, for which I paid approximately $160, and it has still not arrived.

I cannot find any point of contact on the platform regarding this issue, and the total lack of a contact phone number makes this process even more frustrating. I sent an email requesting support, but I received absolutely no response. Buying products from abroad for such high prices shouldn't be this difficult, and customers should not be left completely stranded and ignored like this.

I demand an urgent investigation into who and where my package was actually delivered to, the immediate delivery of my product, or, if that is not possible, a full refund of the amount I paid. I request that my grievance be resolved immediately and that customer support channels be improved; otherwise, I will submit formal complaints to the relevant regulatory authorities.
