Takealot NOT applying their own returns policy

I bought a graphics card for my son. The card did not work from the start. I returned the card with instruction to replace. Clearly in their returns policy they state that the customer has the choice of credit, refund, replace or repair.

As the product did not work out of the box a repair is not acceptable and we opted for replace. The takealot agent Raees is trying to force/bully us into taking the credit and not replacing the product as indicated in our discussions. This is because the product has changed price in the month after the product was purchased. Now they are claiming no stock when the website clearly indicated they have stock, just at a higher price. They are trying to force us to pay the higher price.

Not acceptable....
