No credit or refund forthcoming

I ordered an item from Takealot almost 7 days ago, which I cancelled the very next day. A week later, I still don't have a credit or a refund, and I'm told that the item needs to be received back from the courier (in this case, MR. Delivery, which is an indication of how far Takealot / Kalahari has sunk) before a credit / refund can be processed. I'd like to know why this takes 6 days, is Mr. Delivery based in Angola? I can't be bothered to send any more mails to their helpdesk, and their call-centre is pathetic. I will rather pay a premium and stick with Amazon (brilliant customer service, refunds take a couple of hours, not a couple of years, proper tracking information from RECOGNIZED AND LEGITIMATE COURIERS, a variety of products that makes Takealot look like a ****a shop) - You SUCK Takealot, South Africans deserve better than to be saddled up with this *******!
