No delivery and bad attitude

On the 19th of January 2015 I bought an item from [URL Removed] The parcel was dispatched from Kalahari on the 19th to the courier company for delivery on the 23rd of January 2015. I then receive a missed call from the number *** on the 23rd. I called back because I was expecting a parcel and thought maybe it was the courier company. The lady I spoke to told me that she could assist me as I didnt have the tracing number at that time. On Monday morning I called the courier company again and spoke to another lady. I gave her a tracking number and she told me its incorrect. She told me to hang up and call back with the correct details despite telling her that those were the details sent to me by the online company. I didnt find any other tracing number so I called back with the same number, unfortunately she responded to my call again n rudely told me she cant assist me and I must call Kalahari with a raised voice. Todate the parcel I expected on the 23rd has not been delivered. I feel the courier company failed to do their work and deliver on time. The lady I spoke to was plain rude and doesnt know how to treat customers. I want my parcel delivered asap or Im cancelling!
