Order lost with no feedback from takealot

I ordered a few household items from takealot to the value of almost R4000.00. My original delivery date changed and I could not sign for the delivery at that specific time, so I called takealot to re-schedule delivery. I received both smses and emails confirming the new delivery date. This morning I called to follow up on my delivery which was still not delivered, only to find out that it has been delivered. The person that signed for the package, their name is not on the package and the security at the complex confirmed that they did not deliver it there. My package is missing. And whats worse is that I had to call takealot for feedback, not once but TWO TIMES! Which is infuriating. Their response is that they will escalate it and "someone" will get back to me. But yet no one has gotten back to me. I WANT MY MONEY BAC****!! HOW TO YOU CALL YOURSELF AN ONLINE STORE AND THEN DELIVER SOMEONES GOODS TO THE WRONG PERSON. This is poor service delivery.
