Misleading prices

I went to Rages in Hlahatsi to purchase some Sandals , on displays they wer R104.99 , but when i got to the till it was a different story i was told they are 129.99 . I asked the lady Phumzile Molefe who was very rude to me and had an attitude why the prices are differect , she said they is nothing she can do as that was the price i either take it or leave . I asked to speak to the manager or the supervisor, i was told they was no supervisor to assist me, i Asked just for the name of the manager i was told i cant be assisted , this is quite misleading to clients i need my money back why put a different price tag and at the till its also a different , am so unhappy about this and the staff there is very very rude .No apology or nothing about the mistakes that they do
