Thank you for contacting Acme.  How may I help you today?
Hello, I am trying to purchase something and my credit card keeps getting rejected
Oh, I'm sorry to hear that.  I have a few tricks that might help to fix the issue, but if those don't work, I'd be happy to take your order the old fashioned way
Ok great!
First of all, we'll just need to double check that the card hasn't expired
It is a good expiration date
That can sometimes happen without warning.  Or if the card has recently been renewed, our system might still have the old number

okay, that was worth a try the other thing that often goes wrong as well--and it happens to me all the time--is that the number might be wrong, no matter how carefully it's typed in are you able to copy and paste the number directly from your bank website?  That has worked for a lot of customers in the past
That seemed to be the problem, I was entering it in wrong. Thank you for the help
Ah, you're welcome.  I'm glad I could help May I assist with anything else while we're here?
That is all I needed
Okay, have a great day
