Terrible service from Takealot

I ordered 2 of the Himalaya clear complexion whitening day creams at R275 each. I instead received the Himalaya clear complexion day cream not the whitening cream. This cream is selling at R135 currently. Firstly i received the wrong product and secondly there is a huge price difference. I have contacted Takealot over 30 times to complain and to date they still havent refunded me. They collected the creams for a refund but now they say that the refund is declined. How can they decline the refund when it is so clear that they gave me the wrong cream and over charged. Terrible service from them. Totally dissatisfied. My order number was ***.
