PEP PAXI's reliable not so reliable!

On the 4th a parcel was sent from KwaMashu to be delivered within 5 working day in Pep Home Northam via their PAXI. It is after 3 full weeks now the parcel is not delivered and no one has bothered to say anything. So yesterday I decided to call them and they told me my parcel is lost and that an agent will call me. I am still waiting for that call. They say they are reliable and people should not worry about the frustration of missing deliveries, here I am frustrated from my parcel which they say is lost. I would not advise anyone to use their services, it is really poor and I am never using it again.
