Disrespectful manager

Today I went to ackermans,I was assisted by Maureen. I wanted to lay bye a pair of black pants and skirt. The price on the pants where stretched out with a marking pen however it was visible, and there was no new price/or price to replace the stretched out price. There was one pair that had a price that's similar to all pants that was not stretched out, I assumed that that is the price for all pants since nobody bothered to replace the stretched out price. I was surprised when Maureen told me that the price is higher then I told her that I will not be taking the pants, Refilled jumped into our conversation, she didn't even bother to try to understand what is going,she said the system says it's is more. I asked her how was i supposed to know the price since all of the pants except one had a price, she then instructed me to go show her what I was talking about because that is unbelievable. I had to prove that I was not lying. After proving that I was telling the truth she just said okay. I felt undermined,was treated like a child and a ****,because she did nothing after I showed her that there were no prices. I got ****ed of because I thought the proving will yield some sort of outcome. I asked her if she couldn't prove what i was saying without instructing to show her, she said she could but she didn't believe me. Realizing that I was now livid, she apologized and I told her that I will not accept her apology, she shouted at some ***orker to come and apologize on her behalf, now I look like a hardheaded person who doesn't want to accept her apology. I left her to continue to be assisted. I asked her for her name since she was not wearing a name badge,she told another colleague of hers what transpired, now I felt like a joke,like everyone in the store must just know about me and look like a villain.
