Hello and welcome to AcmeCorp.  How can I help you today?
I'd like to check on the status of my order, but I'm having difficulties.
What seems to be the problem?
I don't remember my Username.  I tried like 5 times, and I keep getting it wrong.
I will be happy to help you with this.  Can I have the full name on your account?
Alessandro Phoenix

Great, thanks so much.  Your user name is aphoenix1. Is there anything else I can help you with today?
Oh!  That's right.  Now I remember. Let me try to log in to make sure it works. Okay, it worked.  Thank you for your help.
