Item never received

I used to love shopping at Takealot.com. I always received superb service, but my last order was a terrible disappointment. I ordered 3 items. Two of them arrived after the delivery date had been moved on 3 times. They arrived in a tiny box. The third item, just so happened to be the most expensive item, was much too big to fit into that little box. I contacted Takealot.com a few times. They say they are looking into it. It has been 2 weeks now with no feedback. How do I get my item or a refund I tried to write a review and they just rejected it.
