想给法国的客户发一封电子邮件，不会法语，也不懂语法，更不知道怎么样和客户谈，求大神指点，请大家帮忙

Dear friend,
Please allow me to apologize to you, because I'v sent you products with poor quality.
I didn't know this problem(poor quality), I would withdraw them from sale after I know that.
You bought the products before I withdraw them, but I didn't give you an explaination,
so that's my fault. Apologize again. I will take responsibility for that.
But I hope you could withdraw the wrangle, because we will get heavy loss from this.
I promise you to deal with this problem as soon as possible, please don't worry.
