High markeups on product

On the 16 January I purchased on sale the Oral B - Pro 3000 Black Edition @ R2,499 on order number Order #***. A week later the same product was further advertised on takealot for R1999.00. I needed to buy another brush and when I check woolworths has it at R1699.00 normal price no sale. I have been purchasing from takealot for years and always found reasonable deals, the pricing on the product is very disappointing as I have now paid R800.00 more on takealot site. I emailed this to takealot and received the response below, which i think is very anti customer behaviour:
