Condescending demeanor Estee Lauder makeup-artist

Wednesday I tried on Estée Lauder make up at Redsquare gateway, the mirrors were deceiving and I bought the makeup, left the shop and got home and got feedback that foundation was too light. Luckily had not opened the box nor the bottle. Went to Pavilion and Linette offered to help and opened my bottle to check if it had been used or not then after tried a different shade on me. She gave me a sample to try for a day before committing myself and said I can keep the bottle I had bought until I decide on a perfect shade. Went back to choose the correct shade and today I’m being assisted by Amanda who was unwilling to assist me just before I could even open my mouth, told her my story, she took the make-up, opened it and told me that I had used it and will not be able to assist me in any way in a very condescending manner and so full of arrogance, I told her what had happed and she did not care to hear what I had to say because she was too busy talking over me and had already made up her mind about my situation. I got really irritated and asked for her supervisor and she Said “No” no else can help me. She decided to call Linette telephonically the one who opened my bootle and came back to me telling me that Linette confirmed she opened bottle but did not mess up the make up, my question to her was: how is it now my problem that the make went to the top of the mouth of the bottle after being opened obviously, and that I didn’t have control of hat the make-up does after being opened. And it fraustrates me that she is so adamant that she’s not gonna help me even tho she is aware her colleague is the one who made a boo boo. Not only did she talk too much she started telling I’m taking things personally and laughed in front of her supervisor who eventually came and her laugh was meant to show me how superior she was at that point. Someone please help me. Because I don’t understand how someone with such an attitude is working with customers.
