Wrong item and terrible service

I have purchased a PS4 controller from them on black Friday and I've received the completely wrong item. After almost two weeks of going back and forth with emails and phone call, I have gotten nowhere. Takealot.com have given me many different excuses ranging from: 1. Item has been switched with someone else's item. 2. Barcode error and I've gotten the wrong item from the start. 3. Courier company error. 4. Warehouse error. I've spoken to many different staff members over the phone and email to try to help me to resolve this issue and they were all of no help to me. One lady did speak to her superior and they said that there isn't stock of my item in the colour I initially purchased it so they can offer me the item in a different colour which I have accepted. After a week of waiting for the new promised item, I phone to check up what's taking delivery so long and they then tell me that there isn't anymore stock yet again and they can offer us a refund and they cannot honour the price of the item anymore. Completely disgusting service ! I will never shop with takealot.com again ! And the most ridiculous part is that I have ordered my initial item at around 00:10 on black Friday, which means that I was either one of the first or maybe even the first person to have purchased this item as soon as their specials had dropped but yet I get told that there isn't stock and they cannot honour the price anymore. Absolutely ridiculous !
