ORDER DELIVERED LATE!!!

NOT DELIVERED ON TIME!!! My understanding in the business world is that you should under promise and over deliver not the other way around. But I don't think Takealot understands this principal. Two of my orders came a day after the promised delivery date, in fact I'm still waiting for my order to arrive which was 1st due on the 16th then delivery date was changed to the 18th and today is the 19th and still nothing... I've phoned them twice and they promised to get back to me and I still haven't heard anything from them, another promise not kept... Looks like Takealot is in the habit of making promises they can't keep...
