Never opt for replace when returning a product to Takealot

Takealot delivered an incorrect product and I requested for the product to be returned. Now I have not had problems in the past because I have always opted for credit instead of replacement. Because they change prices for this specific product (original and sale price fluctuates every week or few days) I wanted, I decided to opt for a replacement to protect myself from buying it at a higher price. I have soon learned that was the worst decision ever. Its been two weeks and counting since I requested a return and the process has been stuck on "Return request being assessed by returns specialist team". I tried reaching out to them via Twitter (verified account) and they took me from pillar to post. Called in, and I was told its been investigated. I am simply trying to return a product and for you to give me the correct one.
