Bad attitude from the delivery guy

The online purchase experience was painless and I had my item 2 days later however the delivery guy (his name was William) needed a whole lot of customer service training. First he claimed he could not find the address on the GPS and wouldn't take any of the directions I tried to give him. The final straw was him telling me that he would take the items back and I "should" collect them from the shop when I have paid delivery fees. Plus on the website it states that if an item is returned you have to pay R99 for another delivery. When he finally understood the directions (thankfully a colleague could speak with him in Sotho) and arrived he was still insisting he was right and I was wrong. This is the reason I am giving just 2 stars. Train the whole customer chain it doesn't just end at the purchase point.
