美国采购需求：天然精油、卡斯蒂利亚皂、护手霜、护肤品

I recently purchased a bottle of organic jojoba oil from your company via Amazon in December. Upon opening the new bottle, I noticed a rancid smell, which is quite unusual since I've used this oil frequently without any issues. The expiration date shows it's still good until 2028, but the odor suggests otherwise. Is there a process for addressing this kind of issue? I would appreciate guidance on what options are available for resolving this matter. Additionally, there's a code printed above the expiration date that might be helpful for reference. Thank you for your assistance.
