4PX Tracking does indeed deliver packages, but the registration can sometimes mess up due to packages coming from Asia (China). You just have to track your 4PX package via 4PX order No. on their courier website (https://www.track.4px.com/#/result/0/4PXOrderNo(usually numbers)). When you get access to information about your parcel there should be a Tracking No. that you can put into your local delivery services e.g. in Sweden we have Postnord; try using the tracking No. in Postnords services (or any other you can think of in your country e.g. DHL) and you should find some information.

On the 4PX website, it said in French "Destinataire absent et informé de venir retirer l'envoi" but when I used the tracking No. in Postnords services I found out that my parcel had already been sent to my local pickup station.
