信用证对方银行提不符点，客户要求降价，怎么？

波兰客户，用BANCO SANTANDER CENTRAL HISPANO S.A HONGKONG BRANCH银行，网上查是西班牙国家银行 按照交单期交单，提出不符点 -受益人写的不是APPLICANT，因为单据要求里面没有标注，就按照提单显示的货人信息拼写，差别在一个是全拼，一个是缩写 -总金额提出要求写56000.00USD，单据写成$56000.00 交单的时候国内银行没有提出这个问题，到对方银行了，因为发报文说有不符点。3.1日跟客户，客户接受不符点。到3.8日客户突然提出他的客户银行破产，要求降价$110/MT。 这票货是赶在春节前出来的，原料成本高，时间紧，为了保客户，插进去的订单，现在要降价，实在没法接受。估计是客户考虑到现在的市场价格下跌，所以自己编出来的理由。我当时回复邮件，不能接受降价，如果实在要降，我自己拿$20/mt帮助你，写明不是公司。当时就想朋友之间互相帮助，多了也拿不了。 期间客户一直没有上SKYPE.一直等到3.12，他们公司别人加我SKYPE，发邮件，要那个货柜。谈了以后才知道，他们老板又要降价到$140/mt,我直接拒绝，回复说把合同不当回事，价格是凭贵司心情来定的么？ 今天跟领导沟通，决定坚决不降价，尤其是后面还有一个柜子。不能这个先例。然后给客户发了一封邮件， I checked with our boss,he can not agree your reduction. We all know the discrepancies which presented by Banco Santander Centreal Hispano S.A are not reasonable according to UCP600,so we he asked our bank to check with them,or their head office in Spain.Also we will send this to our Chinese Embassy in Poland.Business should be based on equality and mutual benefit,and good reputation is very important to a company. We he worked together for two years,and this event never happened.Maybe you had some trouble,but we don't think it is the best way to solve your trouble by this way.Business is not only do one day, lose money today,tomorrow will make money.That's normal.I also sold the same products to other Poland clients,the price was not lower than yours,they paid us without any delay.I don't think your company is worse than others. We hope you can cherish your reputation and our business relationship,but if you insist that you can not take the container,please inform your bank to send a message to our bank today. And also please let me know the following container,what do you want to do? 不知道结果如何..... 纠结！
