kodak randomly adds a thounds rand to product.

Yesterday on the 28-06-2015 @ 13:09 I went to buy a Canon 600D twin lens bundle from Kodak at maponya mall which I saw on the 22 of June for R5999. I went in and told the sales person I'm be back by Monday to purchase it so I requested they keep it for me.as I went on Sunday to buy it, they charged me R7000. I told them I can only pay the R6000 as its even displayed at that price.he took the price notice down and denied I pay the R600 and said it was a mistake,just like that.how do you advertise at a certain price then end up paying mor cause of the mistake of displaying at a wrong price. As a student I had budgeted within the R6000 and adding a thousand on top was an inconvenience to my budget as. Am disappointed with their service.a thousand is a lot to just randomly add to a price.i hope someone out there does something to help.thanks
