Dissapointing delivery plans

The fact that Takealot doesn't have a phone number as well as the tracking system sucks. I want to know what exact time my parcel will be delivered so that I'm there to sign it. Had to move clients around just to make sure that I'm home for the second time between 8am-12pm(that's what the sms said for possible delivery time). I don't get an update of where it is, I have no idea what's going on and no one let's me know or can call me just to let me know they're outside. I should just expect it anytime and also be available...anytime? There should be a client and courier online communication so that people like me don't lose my patience or salary.
