遇到一个超级拽的客户。。。。要不要CANCAL掉？？

谈了半年的尼日利亚客户，终于可以下单了，数量20台，价值几千美金吧， 但是却要OEM ：说明书，机器面板，标贴，外箱都要他们的原厂商标，都是彩印。 因为数量太少这点量根本不了，而且OEM制版费太高了，让他加数量不愿意，付制版费也不愿意。。 我了个去，还一而再再而三的威胁我。。。 真想直接CANCAL掉他。。。以下是客户2封威胁邮件内容，遇到这样的情况？各位福友们，你们怎么应对呢？ Dear Sherry, Thanks for your mail. If you think you can not print the brand name, trade Logo and model number in ORIGINAL on the item's face plate, back plate, on the manual and outer carton, you can forget this transaction because we do not patronize substandard product or production in any and do not give room for any fake. Thank you. Richard. 2013-07-08 Dear Sherry, Thanks for your mail. Sorry we could not accept white sticker as name and face plate. It has to be properly printed as original face and name plate, if you can't print our brand as original, we may forget the business for now and continue with our other associates that always meet our demand.
