Rude workers that don't wanna listen to the customer

I walk in to Crocs Woodmead on the hanger it says was R899 now R699 when I get to the till it's R799 so I ask why they say a customer must have put that there which is not my problem I ask for the manger they send me to Portia habe who is rude and shouting at me and insist that even if I go to the consumer act the price that stands is R799. Because I already paid I will keep this pair for my son but will never buy a pair of Crocs or walk in a croc store because the stuff is rude and u don't pay the price u see.
