Missing parcels and poor communication

I have had two bad experienced with Dawn Wing in a very short period of time: 1. A parcel was handed over to them on the 1st of June. Late Juen I hear that the parcel is "missing" but they didn't report it to the sender or to me. How does a parcel just go missing? Should an investigation not be launched? Someone out there is enjoying 8 bottles of wine that they didn't pay for. 2. I received a notification than a different parcel was due for delivery today. How does the driver let me know that he has arrived, via SMS? SMS??? Really, who uses that anymore. A simple courtesy would've been to state on your tracking system that I should expect an SMS when the driver has arrived. Now I have to wait another two days for my parcel to be delivered.
