Very poor customer service and not willing to assist customers at all

Wanted to buy a men's wallet which had a price tag of R79,99 but scan R89,99 at the till... when i asked for clarity on the price increase the cashier (Nomfundo) said it's either i take it or leave it because it is not her fault that there is a price change and she's not even working at Men's department, she called the supervisor who said the same thing and added that Mrp changes their prices everyday and these nothing they can do about it, i'm so disappointed and don't see myself shopping at mrp if this is the type of attitude they give to their customers when one is simply asking for clarification.
