I purchased a backpack from H&M a few weeks back. One of the zippers broker the first day and the second one broke about a week later. Due to my work schedule of two jobs, I wasn’t able to exchange it when the first zipper broke but when the second zipper broke, I didn't have a choice. I called customer service first and told them I just wanted an exchange and wouldn't be able to go all the way home to get the receipt. I was assured that an even exchange would be absolutely no issue and I proceeded directly to the Galleria at Sunset Mall in Las Vegas where I made the original purchase. I had the misfortune of being assisted by David whom had the nastiest attitude and some of the worst service I received and I felt it was very unnecessary. First of all, even though I was highly frustrated, my initial greeting to him was upbeat and cheerful. I always do this intentionally because I want things to go smoothly. David did not reciprocate my energy. In fact he was incredibly combative immediately. I explained to him that I just wanted to exchange and showed him that I couldn't close the backpack which was full of my daily items. Mind you, I had walked from my job to the mall with a backpack that would not fully zip. What I was trying to explain to him was I needed to get another bag and I didn't want my personal items strewn on the counter. Good customer service would have been showing me where the options for other backpacks are but he just pulled out a shopping bag and slapped it on the counter and waved towards where the bags were. I forgot to mention that the first thing he said to me was that I couldn't get cash back and where is my receipt and that they don't look up receipts by the card used. I never asked for cash back so to me that information was unnecessary. The real issue to me was when I became frustrated and let out a deep sight and perhaps a slight eye roll he has the sheer audacity to say to ME, a longtime customer and grown grown adult, "you don't have to roll your eyes." That is when all bets were off. I do not care what the circumstances are, I will not be chastised as if I am a child by any individual with whom I am spending money or by ANYONE period. He then proceeded to continue to attempt to provoke me by becoming less helpful, more combative and continuing to respond back to everything I said. I am not his child nor was I acting like one and I do not have to be subjected to that type of service. This occurred in front of numerous other customers and store associates. I need H&M to understand that none of their customers of any age comes in to their store to be belittled, humiliated and spoken to condescendingly by any of your associates especially when the reason for my return visit was due to your faulty product. David at Galleria at Sunset was completely out of line and your management and your customers need to be made aware that this type of interaction is unwarranted and unacceptable. I will post this on as many review sites as I can and share this experience with my large worldwide circle of influence. Thank you.
