亚马逊快递需要signature confirmation，客户不满，给了2星review？？

客户下单后，我就马上发货了，因为这件商品价格很高（400多美元），所以我们要求客户signature confirmation（签字确认）。结果今天就收到了他给的2星review：“The only reason for two stars is because we were not told the item required a signature upon delivery thus we did not get the boots in time for our special event.”
你们觉得亚马逊会帮我移除这条差评么？
