客人少付运费的问题

有一个以色列的客人，叫GOLYAN，之前在广交会很豪爽的给我下了一个小柜的单子。期间确认各种细节就有点小不愉快了。货生产到一半的时候说要样品，还要我们付运费。我跟他说样品免费可以，运费不行。后来她又说运费一人一半，我坚决不同意。 后来我写了一封邮件给他，内容如下： Dear ， As you know,our samples are free,so you need to pay the shipping fee.we cannot split the cost with you .hope you can understand . And we need 10days to prepare the samples,pls kindly note it ! If you can accept that ,i will arrage the sample today! Waiting for you reply! 他回复给我： If you need 10 days for prepare the samples so when??you think to load our order?????? Its too late!!!! 她要二十款的样品，感觉我们样品都不需要时间准备的，后来跟他解释了下，因为也是看第一次合作，我很积极的帮他催样品。我跟给他写邮件： Dear, Please noted the following information : 1、? ?? ?? ? When you place an order,we send the photos to you for confirmation , and you said yes ,so we began to product 2、? ?? ?? ? The booking date is about on 15th July as I told, and the shipping date is on the end of this month. 3、? ?? ?? ? For the sample ,because there are twenty items need to finish so need more time ,I he already confirmed with our colleague ,and he said he need 10days to finish , I will push him to finish sooner and send out as soon as possible ,but dear, please kindly noted that??you need to pay the freight fee . 4、? ?? ?? ? Please kindly confirm the above information ,and then I can arrange the samples within today as you know ,the time is very tight . It is our first business ,we don’t know each other better ,so there are many things need us to communicate with each other often ,so I bring so much troubles for you ,I am so sorry ,and I am so grateful for your kindly help and understanding ,thank you very much . I looking forward to hearing from you soon ,??thank??you so much 但是我坚持要样品运费他们要全出。后来她就会我邮件。如下： Please please??try your best to send me the sample and You could even pay all the cost of shipping and reduce our part of total final bill. No problem. I need this items for my big fair and my best seller time, please. I also do not want to get stuck with these products, and succeed at and make another new order. 就是因为这封邮件，让我以为他要全额付运费，就给他预付运费，现在她余款打过来，运费只付了一半，还有三百多美金。如果她不给付的话，我估计要自己扛了。 请问这要怎么呢！ PS ：我在福步上还搜到这个公司，信誉不太好啊。坑爹啊。 货到港了，我还没有给他们电放，她们也不急，听我这边的货代说她那边的货代已经把货提到货代的仓库了。 :') :')
