Zero Client Service Ethic

My son has been saving for months for a gaming laptop which he bought from an amazing company called nerdy.co.za. We have been waiting for its delivery from The Courier Guy. My experience with them has been terrible to say the least. They never updated their tracking website with my item so I could never see where it was in the system. When I called I was told it was on the way to Cape Town and would be delivered today (Friday 20 March 2020). I have had ZERO proactive communication from them. Eventually, I called in again at 4pm on Friday afternoon to see what was going on. My package had arrived in Cape Town and was ready to be delivered at 12pm on Friday however, because they had captured it as 2 pieces instead of 1, they were waiting for another piece from JHB that would never arrive. Nerdy.co.za confirmed their error with them and asked them to please deliver the package today still or on Saturday which they refused to do, even though its their fault it wasn't delivered earlier. According to them, they have every right not to as it was an "economy" delivery and only needs to be delivered on Monday. So, I am sitting with a very disappointed boy who desperately wanted to play on his new device on the weekend, and a massive irritation with a company who clearly has no concept of what client service means. Wake up before you go out of business.
