Worse disgusting and terrible service

I walked in to the Pep Home store in Southgate Mall looking for the salad container , in the shelf there was 6 of them left and priced for R14.99 , as I went to pay at the till now I was told its R39.90 each , I asked the manager who's fault is it that the'v put the wrong price on the shelf , she told me its not her problem and the person who is doing merchandising has already left and guess what she walked away from me while I was talking to her , she is so *********** ,with poor customer service she really needs training on how to be a store manager , maybe she had attitude because im younger than her but really she needs to get a grip and understand that we are customers and we pay her salary, im expecting a written apology from her . I cant believe she told me that's not her problem if there is wrong prices at the store before you organise some training for her please make sure she get a code of conduct on how to look presentable to customers , except for her disgusting service she is also dirty you cant understand if shes a cleaner on the manager im sure even a cleaner in the store looks much better .since there was not assistance I had to walk out of the store.
