Takealot useless order system, cannot be contacted.

I am done with Takealot. I ordered goods which showed in stock on the system. Then to be told that the delivery is delayed as they cannot get the goods from the supplier. Delivery date are moved to a date when my office is closed. Now I cannot change the delivery address, I cannot cancel the order and I cannot speak to a person to resolve my issue. This is not the firs time this same thing has happened. Good bye Takealot.
