美国采购需求：天然油、卡斯蒂利亚肥皂、护手霜、护肤品

I've recently purchased a large quantity of jojoba oil and I've encountered issues with the pump. The first one I received was defective, and unfortunately, the replacement is also leaking from multiple areas. This is quite disappointing as I was expecting a reliable product. Could you please provide assistance regarding this issue? I need clarification on the quality and functionality of your pumps. Are there specific features or improvements I should be aware of? Your prompt response would be greatly appreciated, as I'm eager to resolve this and continue using your products. Thank you!
