Thank you for contacting Acme.  How may I help you today?
Hi there. I'm reaching out because I was charged for an order on my account but I never bought anything.
Oh, I'm sorry to hear that.  Let's see if I can clear that up for you May I ask your full name, or your account ID, before we begin?
Yes, my name is Chloe Zhang
and to verify your account information, I will also need to ask your username, email address, and the order ID
My username is chloez09, my email address is chloez09@email.com, and the order ID is 9559621452
Thanks Ms Zhang I can see in our system that the error was indeed our fault, very sorry about that, but I can clear that up for you right away
Thank you
I'll just issue a credit to your account, and you shouldn't be charged for anything

Okay, that should be all taken care of now.
Thank you very much
Would there be anything else that I can help you with today?
No that's everything
Glad I could help.  Have a great day.
