Takealot Order False Recorded As delivered to Customer!!

I made a purchase of a microwave from Takealot.

Delivery is supposed to be made today before 17:00. However, I tracked my delivery, and apparently it was made and SIGNED FOR by myself. I DID NOT RECEIVE THIS ORDER, and NO ONE CALLED ME TO LET ME KNOW THAT THEY ARE HERE WITH MY DELIVERY.

If anyone had called me to say the delivery will be delayed, I would less upset, but now they have gone on to say "I" have signed for the order. This is a blatant lie which I do not appreciate whatsoever. I paid a lot of money for the item, and there is no way I'm losing that money and the order. I

My phone has been on the entire day, there cannot be any excuse for the mess up in my order. None whatsoever.
