各位前辈，我如何回复客户这封邮件呢？谢谢！

我们是电子产品的，产品使用时要安装驱动程序，为了提高产品优势，我们的产品控制器可以兼容国际上几个比较大厂家的驱动。但如果客户没有特殊指定要兼容这些厂家的驱动，我都发标准的产品给客户（标准的产品是不兼容其他厂家驱动的），一个美洲客户购了几套样品，客户需要兼容其他厂家驱动的，结果我们发成了标准的产品，以下是客户的回复邮件： “Dear Susan, I'm very surprised about this situation! Since the beginning I told you that my client was looking for alternative monitors for IBM, so there is no reason, other than a involuntary mistake, to he sent the monitors with the standard controller. I he recommended more clients of mine (not only in Peru), including big manufacturers like IGT and HP, to use your products. Of course I am confident that you will send at no cost whatever is needed to solve this situation first. This people is ready to buy more product from you, but they need to see this working good first. I will wait for your kind answer, José Miguel” 我们准备免费发几个兼容其他厂家驱动的控制器给客户更换原来的标准控制器，针对以上客户邮件，我怎么表达比较合适呢？恳请各位前辈帮忙，万分感谢！！！
