My Courier SA is a flop!

My courier SA, is a flop! They fail to deliver on time. My parcel is delayed since the 31.12.2025, no delivery and no call was made. On the 02.01.2026 I made a call, where at first I was told it will definitely be delivered, during the course of the day, I check the status, its changed to delivery cancelled at office, and then again to parcel checked in at office. I made another call, where I was told parcel can be delivered next week on Monday, 05.01.2026, I sure hope it does....
