收到agoda的邮件，不懂该如何处理

预定了6月12号清迈的一间酒店，成功预订，但是第二天又收到agoda的回复邮件，内容如下：Regard your Booking, please kindly notice the below message from the hotel and contact us back if you need further assistance:" Regarding to guest special requests. Please inform the guest as below; Twin bed = In that period our twin bed room are occupied." Thank you.Regards,Pia-------------------------------------------------------------Booking Details-------------------------------------------------------------邮件的意思看懂了，就是说我要的双人房没有了，那这是代表着我要重新退款再预订呢，还是，还有房间只是没有双人房了，我还是可以按时去住？？？求解答，这封邮件不能回复~
