Two weeks later, still waiting for an express package

We dispatched a parcel via Fedex, we uploaded the documents manually. Paid for Express to Botswana, Two weeks later it still did not arrive. So I follow up with them, as they are not capable . S today, I f get message they don't have an export invoice. I uploaded it when I made the booking, and I handed the driver a copy ( who told me that Fedex has no idea what they are doing). And now they don't have it? Anyway, 2 weeks later my parcel hasn't been delivered, I'm not getting help, I have no email to send the THIRD copy of the export invoice. The service is shocking, the competence level is ZERO.
