Ordered a product and got R300 cheaper product instead (Although I paid for the original)!

I ordered and paid for 3 High Speed Fan Notebook Cooler With LED Q-SR03 on Takealot. They've sent me Mikuso Shiron-2 Cooler Pad Black [NCP-064 BK] instead which is R300 cheaper. Seriously! I'll NEVER EVER order from takealot AGAIN.
