请问：如何取消与英国使馆的预约？

本来已经网上预约了，可是发现时间比较晚，想提前2个礼拜，又没有人知道怎么取消原来的然后重新预约呢？
记得之前有个发过类似专题，可是找不到
还请知道的人再告诉一次，不胜感激！

自己顶一下,恳请答复!

the step is as when you are making a new appointment. when you select a specific time, they will tell you, you already had one, do you want to cancel or continue( sth like that, dont really remember), anyway, you just choose cancel. then it's done.
