Driver delivered to wrong address, no help a month later!

On 25 June a driver from The Courier Guy delivered an order from Makro that was meant for me to some other address. I immediately called The Courier Guy to confirm that I had been home all day and there had been no delivery and to ask what was happening. The lady at the call centre said it was 'given to number 19' (there is no number 19 on my street), then 'have you checked with the security guard?' (there is no security guard - private residence), then eventually 'the driver dropped it in Rivonia somewhere' (the correct address is in Boksburg). These all sounded like lies, and these calls are recorded...I was told that the issue would be rectified the next day. It has been MORE THAN A MONTH and The Courier Guy has done nothing to fix their mistake. They lost goods that I paid for and have therefore ****** from me! It seems one has absolutely no recourse with this company if goods in transit disappear.
