Extreme poor Takealot service

I ordered two of the same products order #***. All of a sudden Takealot sent me a message to say that the order is delayed. The next message that I received from Takealot was that they lost the order. Eventually when it arrived it was the wrong product. I then returned the product for a refund. Takealot then refunded me, but not into my bank account. They refunded me by giving me credit on my Takealot account. This is wrong and I think this is *****, because I have no product and Takealot have my money!!! Then Takealot did not refund me for the delivery fee!! Again they kept my delivery fee of R35 for a product that I did not receive. Again, I think this is ***** because I have spent R213 and now have R178 in my Takealot account with no product I received. If this is Takealot's business model to make money I want to warn people about Takealot's ******* business model. When I placed the order there was no message to warn me about this policy of Takealot that you will not get refunded into your bank account neither did they warn me that if the wrong product is delivered they will not refund my delivery fee at all.
