WRONG ITEMS

I bought about 9 items on black Friday. It all went well, till i opened up my collection and 1 wrong item was delivered worth R1000 but 3 items that i DID order was never delivered worth ± R1000. So did they just replaced the 3 items with something thats worth R1000 because there is actually no stock of my 3 items that was ordered???? Its my first time shopping online with you guys & believe me i will never make that mistake again. I am still waiting for customer service to contact me back. IF YOU CANT HANDLE BLACK FRIDAY AS A COMPANY WHY DO IT!!!! I need my 3 items urgently. Why must i wait for my items that i have paid for and you guys just take your time to resolve. WILL THIS BE RESOLVED??? I WANT MY 3 ITEMS OR REFUND ME THE MONEY FOR WRONG ITEM & I CAN GO GET SOMETHING ELSE!! I DO NOT WANT THE ITEM THAT WAS WRONGLY DELIVERED!!!!!
