The worst service I have ever received

Firstly, (Dec 9),I was sold a service, for which I paid, that does not exist. I needed to send medication to the UK and I was sold an envelope to send the parcel. Guaranteed 72 hours delivery. Dec 18, I checked with the receiver if the parcel had been delivered, to find that it had not. On investigation, I found that the parcel was in Johannesburg as the service I had been sold did not exist - only documents can be sent. The parcel sat in Johannesburg - no-one ever contacted me to say there was a problem. I was told that if I provided an invoice for customs, the parcel would still be sent, this I did on Dec 18, it was sent to Mandisa who was assisting me. Dec 25, I checked again to see if the parcel had been delivered, and it had not!!! I then said that the parcel should be delivered back to me, with the R300 paid for delivery. I was told that the money could not be returned but a complimentary pack from Pick & Pay (who are the agents for Aramex) would be sent - this turned out to be another envelope to send a parcel locally. What a laugh, I would never use their services again, even if it were free!
