Wrong delivery and false advertising

My last experience with Takealot has been rather annoying. False advertising at its best.

An item I had seen, ordered and paid for was delivered in the wrong color. My order clearly stated Rose Gold. I have screenshots and emails from Takealot. Takealot Delivered Champagne instead. I returned the item same day and told them I don't want a refund I would like the color I ordered. Next day they collected the incorrect order. I followed up 2 days later as i had not heard back from them on when my correct order will be delivered. They have now changed prices and tell me they have credited the amount to my takealot account because they have changed suppliers.

Can someone explain how that is my problem? I paid for what YOU advertised, your price changes should not affect me when YOU made the error. I would understand if I made the error and i ordered the wrong color. I made YOU aware of the error same day.

Its such a small order you cant even get that right?
