Takealot and their constant wrong orders

I ordered a pair of Under Armour size 11's tekkies on the 22nd of December. A size 6 was delivered on the 24th. This was a Christmas gift for my partner. They collected the parcel and credited my account after I explicitly stated that I want my money back, not a takealot credit. Needless to say I rocked up empty handed on Christmas day. That's not all... I ordered a size 7.5 UK Under Armour tekkie on the 31st of December, guess what!?? A size UK 5 arrives. Can they JUST NOT get an order right??? I now again requested to pay my money back because I am sure the amount I paid and what the shoe cost now isn't the same AND their excuse will be no stock. This is ridiculous!
