I had two international parcels which have been sent to JIMC because Centurion PO say they were not collected. There is a track and trace website of which I have been using to keep track of my parcels. I realised 3 of my parcels have had the status that they are at Tshwane hub for quite sometime out of concern I called the centurion post office to call them and enquire about them. I was told they do not have them. I decided to visit the post office to enquire. I found a lady who had not intentions of assisting me she just handed me a log book without explaining to me how it work. I saw my name written in it and then she told me that it means thats the only parcel they have. I tried to explain to her that I have a concern that , the parcel shows to be at Tshwane hub what are the chances that my other two parcels are also at the office. She just told me that there was no more she could do for me. The very next day I check the system it was updated from Tshwane hub to Centurion (out of office) to JIMC in transit. But there is no record of my parcel at Centurion. I called the help desk and Centrion Po to help me retract my mail mo one is willing to assist i need my parcels
