Lost shipment to Namibia

I sent a parcel to Namibia on 20 November 2019, after trying to track my parcel with no luck, and phoning non stop for feedback i was told by Richard on 5 December 2019 oh sorry your parcel has been lost, we will submit a claim to get you refunded between 6-8 weeks. phoned today for feedback and Richard is on leave even Hendra the Manager can't assist me, she has also not been of any assistance regarding my missing parcel. Beyond disgusting service!!!!
