尼日利亚客人非要给他弄邀请函

近来跟了很久的一个尼日利亚客人，寄过样品，他们也付了一百美金的样品费，说要下七万多的单，可要我们给他们弄邀请函来中国，这个公司叫eud-brazil nigeria limited,很多帖子上讲都是个骗子公司，从06年始，，今天我跟他们讲邀请函无法搞到手，要不先把定金打过来，好安排大货，其实我们根本没去弄，他们就讲“pleased with your news and we are very disappointed on this news and kindly note that we are not sending any fee anymore due to your authority dose not believed your firm, due to if your company is well known your local city authority will approved our trip. anyways thank you so much for talking with you but now is better i look for another shipper whom will work with us. he a nice days and bye” 这个公司运行这么多年不倒闭呢！@？
