The Courier Guy need to spruce up their act.

I have made a purchase from amazon which was supposed to reach me 2 December 2024 through The Courier Guy. They duly informed me my parcel was out for delivery as early as 7.30am. They said the parcel would be delivered by 18:00. I was at home the whole day, unable to move, for fear they would turn up in my absence. They never showed up. An sms message later said they attempted to deliver but there was an issue. My further engagement with them reveals that they came and found nobody. How can this be true. Courier people never come without making a call? Even now I am busy engaging them. I see no urgency to ensure they deliver today. The Courier Guy need to spruce up their act. When is my parcel arriving?
