Tracking number informs me that my package was delivered but I didn't receive anything

We already explained the reasons your package might not get delivered here.

But do you know what to do when the shipment status informs you that your package was successfully delivered, when in fact your item was not delivered at all?

In this scenario, the best to do is to get in touch with the carrier responsible for your package. They can tell you what happened and what you can do to solve this.
