Passport Shipping

From our experience of working with Passport the company felt like a scam. Only few of our shipments arrive on time. Often they are 3-4 weeks late and several never arrived. The tracking gives almost no information about the whereabouts of a package. And the shipments go out with shipping companies nobody has ever heard of: Amarex, Fleet Optics, Colis Prive. Who are these companies? Passport, have you ever heard of Fedex or UPS?
