Late deliveries

I can see from the tracking that my parcel has been sitting in Cape Town this whole week, not being sent out for delivery. So I phoned several numbers, all eventually get cut off. The whatsapp option - no reply. The live chat yesterday - no reply. Today at least they rep**** via the live chat. seems we have to wait another week. But they can't give a date at all. Reason given: their courier has been ******. Then the chat was closed. Next week will unfortunately be too late, we needed that package this week. The delivery window given was 4-8 Dec. You failed on your customer service and just have the attitude of a Government department i.e. wait and see? Other businesses make plans around problems to service their customers. A good company communicates delays and reasons before it happens, and not reactive.
