美国采购需求：天然油、卡斯蒂利亚肥皂、护手霜、护肤品

I really appreciate the quality of your product, but I've encountered an issue that I need your help with. I recently opened one of the bottles and unfortunately found that it has gone rancid. This was a surprise because I only discovered it today. I know the return window on Amazon has passed, but I'm hoping you might assist me in resolving this problem. Any guidance or support you could provide would be greatly appreciated. Thank you for your attention to this matter!
