No prices on items then given wrongful informatio

I stopped off at the bellville branch to look for a dressing table for my 3 year old daughter. When I got to that department there was various dressing tables. The one I wanted didn't have a price so I ask Mary who was walking passed me to please go find out how much it is. While she walked I heard her asking the people in the front they said R399 but she insist they must scan it which they did then. She came back to tell me it's R129 it's nice cause it was always R399. I rep**** if it's R129 then I will take it. I shop around a bit more and on my way to the tills I heard Mary say that she doesn't know how they gonna tell me they made a mistake. I took the item cause twice it was confirmed by Nelson and the lady cashier there. Then to get to the till and blame their system and then the manager Charles tells me if I feel like taking it to the cpa I must do it. When I ask hom if his going to do anything to rectify the situation he said he can only get 10% as the price they said is wrong so from R129 to R399 I don't think it's right to treat a customer like that. I went back to take a photo if the shelving which shows n prices. The other item I took was also priceless.
