美国采购需求：天然油、卡斯蒂利亚肥皂、护手霜、护肤品

I recently encountered an issue with the pump associated with one of your products. It appears to be non-functional, and I'm looking for some guidance on how to resolve this matter. Could you provide information on troubleshooting steps or potential repair options? Additionally, I'd appreciate any details about the product specifications, warranty coverage, and whether replacement parts are available. Understanding the options will help me determine the best way to address the situation, as I rely on this item for my operations.
