Undelivered parcel and lies from customer service consultant

On the 18 March I went to courier guy CT airport to send 3 piece parcel. I specifically asked for service that requires my parcel to be delivered by Monday the 24th. Monday my parcel was not delivered, I called their customer 5 times spoke with Lerato twice who told me my parcel would be delivered before 4pm. I called after 4pm she told me that the driver is still on his way. I also spoke to one consultant who confirmed with their operations manager Matthew that indeed the parcel will be delivered. I was also in awe that driver had portion of my parcel and the other portion was at the Boksburg Kiosk how I don’t know and no one could give me explanation. I am soo angry at the lies and misleading that I got form the consultants, the inconvenience of not getting my parcel on time when I had paid full amount for the services to get my parcel delivered on time. Not to speak about my airtime to call the customer care with no one offering to call me back. The same Lerato said she would call me back and failed to do so. It’s sickening what is happening because delivering the parcel a day later is useless for me and it’s purpose. Am soo disgusted at the service I received from the courier guy after paying so much to get my parcel delivered.
