Mysterious sudden price hike on items on the floor

I tried on two formal jackets with a price tag of R 199.00. I then left the shop for about 15 minutes on my return,the prices were removed from the jackets.I went straight to the till to enquire about the sudden changes. The price had escalated to R 229.95.

That left me very dissapointed because when I made up my mind to buy the jackets it was at the price or R 199 which is less.I tried explaining to the cashier who then called her colleaugue. Although i explained my disatisfaction with the sudden price increase they didnt budge.

This is unfair.
