Unhappy with service and sales of Takealot

I ordered and paid for a Keyboard Yamaha E473 with stand from Takealot,the exact amount they gave me to pay.They send me a few days later a cancellation of the item. When I searched again on Takealot I found the same keyboard for sale but with a higher price.So the only reason I can think of is that they cancelled my order is because of the price.
