Discovery miles **** on takealot

I'm not happy with takealot as it shows online that if you bank with discovery you will recieve discovery miles on some orders when placing the orders.

Once you go to checkout when finishing the order process it only shows that you can redeem e bucks and not discovery miles.

I don't know if their system is broken but it's happening on many orders even where I've ordered for example a TV for 9thousand I was suppose to get 9000 miles for the order which I never recieved. Someone please explain why you are lying to us????
