INCORRECT SALE PRICE

My son purchased an Adidas jacket online from Sportscene which was on sale for R549. When the jacket was delivered the price marked on the jacket was R399 and I sent an email to Sportscene customer services on the 9th June and all I received was a generic email stating that they have received my query and it was sent to the relevant department. Till date I haven't received any response from them regarding the different sale pricing? Not happy with their service!!!
