Warning! The Sizing Is A LIE

I need to warn everyone about my recent terrible online shopping experience. I was so excited about the dress I ordered for an upcoming event, but when the package finally arrived, the quality was completely lacking and the sizing was wildly inaccurate despite following their guide. My final, very frustrating conclusion after struggling to even zip the item was that this is merely a "Good and cheap place to buy ladies dress," nothing more, and certainly not worth the stress. I felt compelled to immediately leave a review and engage in a dialogue with customer service to try and secure a refund before I missed the return window.
Customer: I am extremely disappointed with the dress I received. If you cherished this article therefore you would like to collect more info regarding ladies spring blazers i implore you to visit our web-page. It looks nothing like the photo online, and the fit is terrible—I followed your size chart exactly for the medium, but it fits like an extra small.
CS Rep: I completely understand your frustration regarding the fit and the perceived mismatch with the online image. I apologize that the item did not meet your expectations. Can you please provide your order number so I can look up the specific dress and review the quality specifications?
Customer: The order number is 988E. Honestly, based on the materials and the fit, I realize now this is just a good and cheap place to buy ladies dress, but I expected much better quality control than this. I need to know the process for a full refund because this is unwearable.
CS Rep: Thank you for providing that. I see the details here and acknowledge your comments about the quality. We certainly take quality control seriously, and I am sorry this particular piece missed the mark. We can absolutely process a return for you. I will email you a prepaid return shipping label right now, and once the item is confirmed back at our warehouse, your full refund will be initiated immediately.
Customer: That’s the least I can ask for. Please ensure that label is sent right away. I don't want any further delays on this return.
The reason I left this review on the website is to hopefully prevent others from falling into the same trap.
