Online order not delivered

I ordered items online from Le Creuset on the 29/06/2020. On the 30/06/2020 I received an email from le Creuset with my shipment number for Aramex to track my order. Tracked every day with no movement on my parcel from the 01/07/2020, last data said on it way to final sorting facility, suddenly I receive an Sms and email from Aramex thanking me for using them and that I confirmed receipt of goods and signed by myself on the 20/07/2020 at 2:56pm. I can prove by video footage outside my gate that no one had been there the whole day. I had in no way received my order. Before this obsurd allegation, and during my wait I emailed the Le Creuset online manager with no feedback from them at all. I called Aramex after the first Sms on the 20/07 and complained, said they will investigate, called them again later that same day, still investigating, This evening 22/07 I receive another Sms from Aramex(Dear valued customer, kindly note that your shipment number LSA***, was delivered on 7/20/2020 2:56:00 PM signed by ANNELINE CONFIRMED RECEIPT.) I am so ****ed off right now... I've been waiting 3 weeks now for an order that costs alot of money, which part of it was meant to give as a gift for my sisters birthday. I really want to know how this is possible.
