Aramex South Africa - Unreliable

Aramex is not reliable at all as advertised. I placed an order with a store on Sunday and they selected to use Aramex to perform the courier duties. I received a message on Monday that the shipment was picked up for delivery to track. I understand that it is busy season. Normally we get the delivery then the next day. I expected my order to be delivered then on Thursday (which is 72 hours later) this never happened. I called Aramex 3 times on Thursday. On the first call I was advised that the matter is escalated and they will call me back. 2 hours later no one called me so I called once more. Still they are working on the case. I then received a call from my manager that her shipment arrived which she only placed on Monday. She confirmed that the courier advised my box is in Johannesburg branch but wasn't allocated so he wasn't allowed to take it. I called again at 16:00 only to hear from the agent that my shipment is not in Jhb. They are lieing I advised of the call from my manager. I have teacher gifts that had to go out on Friday for my customers and now I couldn't deliver to my customers and the teachers aren't getting my gifts. I am out of pocket as I don't have the stock and no gifts. I was advised in the 16:00 call the manager is still working on this matter. Next moment I receive a whats app that my shipment is delayed and I must wait 72 hours!!!! This is unacceptable!!! I already waited longer than expected. I demand a full refund on the stock purchased that I no longer can provide to customers. I also have to stock for the market I am attending tonight due to this matter. I demanded overnight delivery and this never happened. Now my customers will not use my service next year again so I am loosing even more money due to this lack of service!!!
