False advertising on Takealot and dodging refund

After having to wait over two weeks for delivery, Takealot sent me a product that was falsely advertised as a 1260watt machine, yet the machine was only 850watt. The ******* was promptly put back in it's box, the online return form filled and made available for collection. They keep delaying and rescheduling the collection date and thus, my refund. Takealot, I want my refund for the ******* you sent me, whether you pick it up or not!!
