incorrect packing of order

I ordered Led Anti-Collision Strobe Light With Wireless Remote Control via takealot , on web site clearly shows 2 units, when box opened at home only 1 unit in box and not 2 as per the web site . https://www.takealot.com/led-anti-collision-strobe-light-with-wireless-remote-control/PLID***5

in the box there space for 2 units only one space filled the other has nothing . this is really not on , i require 2 units as per the pic on their web site .

i wanted 2 weeks for nothing only to receive 1 unit , half my order
