买了megabus的票, 没有收到确认邮件

前
几天在megabus上买了华盛顿到纽约的车票, 收到的邮件只是缴费成功的邮件, 而且这个
邮件不是megabus发过来的,没有收到订单的确认邮件， 所以我现在手里什么信息都没有，到时凭什么去乘车？想问下大家, 大家买了megabus的票之后有收到megabus发过来的确认邮件吗?
我是四月份买的七月的票，后来我发了个邮件给megabus,就说我没收到确认邮件，结果他们回复我以下内容：“Unfortunately, upon viewing your email we seen that your trip has passed so we hope that you were able to receive more immediate assistance. However, if you have any additional questions/concerns please feel free to let us know.”这段话怎么理解，怎么说我的旅程已经结束了，希望有大侠能给与答复，万分感谢！！！
