Takealot just doesn't answer complaints they don't want to hear

Takealot just doesn't answer complaints that they don't want to hear - I got a message that the driver couldn't deliver my order because I was unable to accept delivery. This wasn't true as I had been available to accept delivery the whole day. When I raised the complaint with Takealot their response (twice now) is just we're pleased you received your order, eventually. They need to tell their drivers not to blame the customer if the driver has a problem delivering on time.
