I recently ordered RGB case fans from Amazon South Africa

I recently ordered RGB case fans from Amazon South Africa. This product showed it is in stock and payment was made. The next day my order was cancelled. The seller, Mixbox rep**** that last item in stock was broken and that was why they cancelled order. I received my refund in a days time. I ordered from Amazon South Africa again and this time they send me the wrong item. I needed the 4 pin fan plug and they send me the 3 pin fan plug. In description you can see that it clearly shows 4 pin fan. Also the fan blades is 7. On the box it reads 9 fan blades and 3 pin fan connector. This discription was wrong. I also checked other sellers and it seems to me that this fan only comes out with 3 pin fan connector. I had to ask for a refund again. The best of all I was a first time buyer. I am done with Amazon South Africa. I will rather buy from BopShop their sevice is the best.
