Makro Online Unreliable

I ordered something through Makro online on the 23rd of August '19 - received a shipment confirmation on 26 Aug '19 stating that the expected delivery date is 30 August '19. I have had no word from them since that e-mail. I've sent two e-mails to *** & *** on 02 Sep '19 and received no reply. I phoned their so called "Customer Care Line", which is a share call and had to hold for 10 minutes just so I can be told by the operator that she can see I sent an e-mail, but they can't tell me where my parcel is, as according to their system it should have been delivered on the 30th of August - all she can say is that it is with the courier company. I had to demand that I be given the info of the courier company and tracking number, as this info was not even offered to me. Nobody on their side was apparently even planning on following up on the matter. Pathetic! Will NEVER make use of Makro Online again!!!!!
