PATHETIC SERVICE FROM PAXI AND PEP STORES CENTURIOON AND CALL CENTRE AGENT

I would like to lay a complaint, I dropped a parcel at PEP Stores centurion (P6358) on the 28th of November, Parcel D ********** 63215. I called their call centre on the 03rd of December and was told that the parcel would be delivered by Wednesday the 5th od December. Today I contacted your their call centre again and spoke to an Elton who refused to give me his surname or a reference for the call, the time was 10:00 when I spoke to him, he just told me to go collect the parcel, how can I be told to go collect a parcel I want delivered? The service I received was very poor, I paid for the parcel to be delivered in 3 days, its more than 7 days and the parcel is still not delivered and I am not told to go collect the parcel. This is very disappointing because we use courier services in the hope that our parcels would be delivered to their destinations on time and when that is not done we atleast expect a proper explanation. My contact number is ********** 020
