WRONG ORDER DELIVERED - NO ASSISTANCE

I ordered an electric blanket BUT instead, they delivered 120 toilet rolls! There is a big difference between the two. I tried the following: - I told the Driver it was the wrong order, he said, sorry, I must handle it with Takealot, as he is outsourced. - I have emailed Takealot and they say I must log a return on the blanket... A RETURN ON WHAT??? I did not get the blanket in the first place ... Although I ordered and paid for it and the system says DELIVERED... PLUS I still want the blanket which was on special when I ordered so If I need to do a new order I must pay more PLUS no guarantee I will be refunded for the initial order? - The call centre number does not work. I ordered this brand because delivery was available immediately instead of the one I actually wanted because I did not want to wait 9 working days, and now, I have no idea when the correct order will arrive. - I have no proof that the incorrect order was delivered as I had nothing to sign to confirm the order was wrong. WHAT NOW???
