incirrect pack size advertised

I ordered a 1.1kg Pro Nutrition Whey Protein off the website on 31st July for R265.00<br> <br> A 907g tub arrived, when I queried the difference I was told to return the product for a refund - really not helpful as I want and need the product and have started consuming it!<br> <br> So I have paid for what was listed as a 1.1kg unit size, received a 907g unit and the response to my complaint to Takealot was that the website listed the wrong size in error, and my only 2 options are to return it for a refund (do they want a half full tub back?) or I can keep the incorrect product. <br> <br> How is this a resolution to my complaint? I purchased the product based on the details they provided which are incorrect and the only solutions they can come up with are that I return the product (and what shall I do then? Besides take my business elsewhere?) or keep it? Unbelievable.
