Waiting for their driver with ZERO communication

I placed 2 returns with Takealot who use Skynet to do their couriers. Today is the 21/12/2017 and I have been waiting for them to pitch up since Tuesday 19/12/2017. Chances are I will go into 2018 still waiting for them. Nobody can assist. When I call the call centre, they don't know anything about takealot returns. When I speak to management, they promise to get back to me, but nothing happens. This is just pathetic service from a pathetic company.
