Thank you for contacting Acme.  How may I help you today?
Hello I am trying to purchase something but my credit card keeps getting rejected
Oh, i'm sorry to hear that.  Let's see if we can get to the bottom of this May I ask, first of all, that you check the expiration date on your card.  Sometimes our site is still holding onto an older version of your card and that causes errors
I double checked all that
I see, and were you able to copy and paste the card number from your bank-account website?  It can be very easy to get a digit wrong, even when double-checking It happens to me all the time
Ok, I think that worked. Thank you for your help
Ah, I'm glad to hear that, and you're welcome. Is there anything else I can help you with today?
that is all
Excellent, have a great day.
