Hello, how can I help you today?
I have a promo code that states "invalid" when I try to use it.  Thanks.
Glad to help. May I have your full name please?
Albert Sanders
Thanks Albert. How long ago was the code issued?
nine days ago, I think
then I think it is out of date because it was issued more than 7 days ago. anyway I will check it for you.
oh, thanks
I will issue a new promo code to you.

It is C22Y8.
Thank you very much.
You are welcome. Is there anything else that I can help you with?
No, thank you!
Have a nice day!
