Shocking delivery and customer service

I am expecting delivery of a fibre router and was told it can take up to 5 days. I did not get a notification or tracking number as yet by Friday 8 November. At 14.39 on Friday, I get a call from a lady saying that Dawn Wing was at the house to deliver? I told her that I got no notification that they will delivering anything that day. I told her I would be home in 10 min and asked her if they will wait or come back and she said she would let me know. I got home within 10 min but they had already left. She did not phone me back so I had no idea if they were coming back or not. I phoned Dawn Wing to ask for assistance and went through to a Charlene. I was told very rudely that she cannot help me because I do not have a tracking number. I tried explaining to her that THEY PHONED ME and that I did not have a tracking number as the lady was going to phone me back. She was very rude and offered me no assistance whatsoever. I just kept being told, Sorry she can't help me and that the lady obviously had my details open when she phoned. So couldn't she then use my cell number just to see who phoned me???? I work in the same industry and will go out of my way to assist a customer. Your lack of service is appalling. I even tried phoning mweb to see if I could get a tracking number but to no avail. So I sat at home, waiting for the rest of the afternoon not knowing if they were coming back, which they didn't. It's Monday morning and I still don't know when they will be back to deliver my parcel. What am I supposed to do, sit at home for 5 days, waiting for it to be delivered?? I have 2 young kids that need to be fetched from school as well as a life. I cannot just sit at home all day waiting for a delivery. Other courier companies have the courtesy of sending a message to clients to notify us when to expect delivery. Your delivery and customer service is absolutely shocking to say the least.
