美国采购需求：天然油、卡斯蒂利亚肥皂、护手霜、护肤品

I recently purchased one of your products through Amazon, but unfortunately, it hasn't met my expectations. I would like to initiate the return process as soon as possible. Could you please guide me on the necessary steps I need to follow? Any information regarding the return shipping label or instructions would be greatly appreciated. Additionally, if there are specific conditions or timelines I should be aware of while returning the item, please let me know. I want to ensure that everything is done correctly and in a timely manner. Looking forward to your prompt response so I can proceed with the return accordingly. Thanks!
