Bad customer service and rude staff

I wanted to purchase a hot wheel play set today it was marked for R129.00 at pick a pay hyper centurion . When the cashier scanned the item it was marked for R 599. I informed Maria that it marked on the shelf for R 599 .she called the superviser where they made remakes in a language I didn't understand and laugh. I took the supervisor to where it was mark for R 129.00. She informed me rudely that I was suppose to check the barcode. Where I told her to please call the manager. As there at six of the same items placed on the shell with the same price .

MANTLA the manager arrived and told me very rudley that I was suppose to look at the barcode and that I am suppose to know prices. By now my toddler of 2 years is screaming because he's hart was set on this hot wheel set . I was just told sorry that the price take it or leave it . My Question to him was thats the price in shelf . He just rudley told me sorry I was foced to leave the store without any help and a disaponted toddler. It's the worsed customer service i ever received.
