In order to best assist you, Zhang, as a one-time exception for you, I'm happy to forward a request to get your order returned to our warehouse instead so you won't need to refuse it. We will make all the effort to get your order returned to us, but due to some factors that will not allow us to make or complete this request, please be advised that it's not a guaranteed service.
这段邮件看得不是很明白，是说很乐意召回订单但是由于不可抗力因素不能这么做？那为什么不让我拒绝签收？
