之前在PDS下单后系统发来一封邮件，给出了快递单号；但是今天又收到一封邮件，内容如下：
Dear Customer,
We have noticed that you attempted to place an order with us within the last 30 days. Unfortunately we were unable to process your order due to a discrepancy with your billing address.
If you have already replaced your order, please ignore this e-mail. However, if you still require these items please reply to this e-mail reconfirming your correct billing address and one of our customer service agents will re-process your order for you.
If you have any further queries please do not hesitate to contact us.
Kind Regards,
The Customer Service Team
Pro-Direct Sport Ltd
请问我需要回复他们吗？
