电话凭证的三个注意是什么？
What are the three considerations of telephone vouchers?
第一，凭证必须拍摄清楚，完整；第二，凭证的有效期必须在三个月以内，这里的有效期是指的开票的时间，比如现在是六月，凭证的开票时间最早也只能是三月；第三，运营商只相信电话凭证，其他的都不用解释，有些人嫌麻烦，不愿提供，让我们与运营商去求情，不好意思，任何人，都不能通过求情去解决事情。
First, the vouchers must be photographed clearly and completely; secondly, the validity period of the vouchers must be within three months. Here, the validity period refers to the time of invoicing. For example, it is now June, and the earliest time of invoicing of the vouchers can only be March; thirdly, the operators only believe in the telephone vouchers, other things need not be explained, some people dislike it. Trouble, do not want to provide, let us and operators to intercede, sorry, no one can solve things through intercession.
