Takealot return policy

Terrible service. I ordered a fan on the 24th of January, I only recieved it on the 15th of February. The box had been previously opened and resealed with tape en plastic wrapping. On assembly of the fan, I found the fan blades to be missing from the box. I returned the item and got credited yesterday with the amount that I paid for the fan. When I tried to re-order the same fan today, the price was almost double. The operator simply told me that the original price that I paid cannot be honoured and that I will need to pay in the difference if I want the same item. How on earth does that make sense?
