瑞典采购需求：天然油、卡斯蒂利亚肥皂、护手霜、护肤品

I'm reaching out regarding a recent order of Argan oil I received from Amazon. Unfortunately, the oil has gone rancid, and I'd like to request a refund for this item. I've ordered other oils from your company, and they were great, but this particular one isn't up to standard. Could you please assist me with the process for returning this product and obtaining a refund? I appreciate your help in resolving this matter as soon as possible. Thank you!
