根据自己的理解写给你参考:
Firstly,i am in well receipt of the another email you sent,thanks a lot!
Secondly,i am really puzzled,i have been very carefully to this glasses,how it comes to split broken like this without any reason.
I have been using glasses over 10 years,never met with this situation,if the life-span of this glasses only 2 years?
I do trust famous brand by their good quality and credit standing,it turns out worse than cheap glasses say two or three hundred bucks,it's really depressed and disappointed!
And i do looking forward to your reasonable comments,thanks!
