Stole someone elses package, did not deliver mine, refuse to correct the issue.

I paid to have a small box containing VR equipment with the waybill taped to it shipped from Somerset West to Newcastle and what arrived was a green blouse in a bag with a completely different waybill number. Ok. I contact these jokers to have them rectify the mistake and they left it up to me to figure out what was going. I contacted my estate and they confirmed that Courier Guy never picked up the package. Courier Guy says they arrived and there was no package for them to collect. Mind you, their driver called me 5 minutes before arriving for pickup and I reiterated that the small box is ready with the waybill attached. What this driver decided to do was ***** a blouse that was in the security area, package it, then ship it. AFTER I CONFIRMED IT WAS A BOX WITH WAYBILL ATTACHED. For some reason, it did not occur to him to call me again when he says there was no package matching my description. Sharron Botha seemed to be my main contact at Courier Guy and what a shining example of what is wrong in customer service in South Africa. Her conduct was both extremely unprofessional, anti-customer, and just overall unpleasant. Courier Guy would not only refuse to refund me for the botched shipping, but they also insisted that I pay them again, even after they 100% failed at their first attempt, to ship the package once more. The absolute stupidity to ask me to pay them again to do something, their core function as a business, that they failed at is beyond reason. Do these employees consult at Eskom or something? Stay far away from this terrible business that refuses to admit its own mistakes. They have fundamental issues with their operating procedure. And if you ever get Sharron at the end of any issue, good luck.
