Aramex not responding to urgent delivery request.

I have recently made a purchase on Amazon and the order was split into 3 shipments of which 2 has arrived in South Africa. The 3rd shipment as per tracking done has been in Dubai since the 8th Dec and have sent numerous requests since the 16th Dec requesting for an urgent delivery to be made to South Africa to allow for a timeous delivery to Namibia by the 23rd Dec. Aramex records the request but fail to communicate any feedback on the request submitted. Subsequent to this order another 2 orders have been made with Amazon of which the one was sent with DHL and was delivered already to Namibia, the other order was also shipped with Aramex and hopefully this will be delivered to my office tomorrow in South Africa for delivery to Namibia. The delay on shipment *** is very upsetting and frustrating and had no alternative but to report this on a bigger platform to get a response from Aramex. Regards Risa
