Pathetic Service from The Courier Guy

I sent a parcel from Brackenfell on 20th January to Libode and I paid R199.75. I was told it will arrive on on Tuesday the 23rd January. The parcel has not arrived and I keep on calling The Courier Guy and I was told it will only be delivered on the 29th January. I am so disappointed with the service especially having paid so much and no delivery even today. Can someone explain where my parcel is and when will it be delivered.
