I'm calling to tell you that the merchandise ordered last month has not arrived yet.
I'm sorry, hold on a moment. I'll check it out. But we have already shipped it to you last month. Would you like us to contact the express company to know what's going on?
Please find out the reason as soon as possible. We are in bad need of it.
Ok, I am terribly sorry for the trouble you are getting into.We will contact you first thing, once we know the reason.
