Aggressive and rude sales associate

[May0500]

Dear Sephora Customer Service Team,
I am writing to complain about a highly unpleasant and unprofessional experience I had at your Tysons Corner, Mclean, VA on December 28, 2025, around 4-5 PM. As a loyal customer who frequently shops at Sephora for beauty products, I was deeply disappointed by the treatment I received from one of your employees.
On that day, I was browsing makeup aisle and looking for a particular product from Dior. Unfortunately, there were no testers or samples available to try it. In an effort to test the product before deciding whether to purchase it—something I believe is reasonable when samples are not provided, I carefully opened a sealed bottle to swatch or smell a small amount.
Immediately afterward, an employee a female associate with name tag reading Delia or Dalia, wearing a black suit approached me in an aggressive and confrontational manner. She began harassing me, raising her voice shouting DON'T TOUCH and DON'T OPEN IT, and accusing me in a way that felt intimidating and embarrassing in front of other customers. When I told her there is no sample available she said that they are out of sample, at no point did she offer any assistance, such as suggesting an alternative product like or " I can help you. What shade you are looking for?", providing a proper sample, or helping me find a tester. Instead, her response was solely negative and lacked any customer service orientation. This made me feel unwelcome and uncomfortable and humiliated in the store, to the point where I chose to leave without making a purchase. When I asked to speak with the store manager she lied she is the manager. When I told her "no, you are not the manager", she replied that they don't have a manager here. Finally she find someone name Alfredo who seemed doesn't care what happened. Instead he told me if there is no sample available I should call the sales associate and ask for help. But why when sales associate  Dalia or Delia came over to harass me she didn't offer her help. He was also rude and  never apologized for what happened and walked away. 
I understand that stores have policies regarding product handling, but I believe customers should be treated with respect and offered help rather than immediate confrontation, especially when the lack of available samples may have contributed to the situation. Sephora has built a reputation for excellent customer service and an inclusive shopping environment, and this incident fell far short of those standards.
I kindly request that you investigate this matter, including reviewing any available security footage from the store on the date and time mentioned, and provide appropriate training or feedback to the employee involved to prevent similar experiences for other customers from the highly incompetent and dishonest person like Dalie (Delia). I would also appreciate a response outlining the steps you will take to address this complaint.

Thank you for your attention to this issue. I remain a fan of Sephora’s products and hope to continue shopping with you in the future under more positive circumstances. Please feel free to contact me at the email or phone number provided above if you need any additional details.
