Marked -Up Price on an item on priced to go rack.

I bought a white dress yesterday 04/04/2016 at Legit, Eikestad Mall, STELLENBOSCH. This item was on the rack of priced to go items and end of range. When I got home I wanted to remove the tag on the dress and saw that the price was on a sticker stuck over the tags original price. The tag attached to the dress priced at R199,99. The sticker that was stuck over the tag had the same details but the price was marked up to R229,99. How can a dress on the price to go rack be marked up instead of marked down??? Unacceptable behaviour. This was not an item accidentally placed on the wrong rack as is only one of the last two items of that dress left, that's why it was on the rack. When I was contacted back from the store regarding the complaint I was told by the manager that it was head office/Edcon that gave them the prices and told them to mark up the price. So what dodgey practices is this that Edcon enforces in their stores??? To mark up prices on items on the priced to go rack???? There is no other retail store that practises this procedure of sticking stickers of mark up prices on items that are meant to be priced to go. So I got no mark down on a priced to go item.
