I ordered a parcel delivery from the UK to the USA and I paid for FedEx Priority service but my parcel was 5 days in the UK (and still in the UK) and no one knows when the parcel will be delivered.
Before, when I ordered on the FedEx website the same Priority service it was 1-2 days for delivery sometimes on the same day.
Maybe they take money for FedEx Priority but you get FedEx Economy services.
