Hi, there!  How may I help you?
Hi, I can't figure out why my credit card keeps getting rejected.
Oh no!  I can help you with that. Please try entering your credit card information again.
Ok, I'm doing that It still says rejected
Okay, try logging out of your account, then log back in and see if that works.
Ok, 1 sec. Ahh, that seemed to do it. I didn't even think of that. Thanks a lot!
Awesome!  Glad to help you.  Can I do anything else for you today?
No, that is all I need.
Have a great day!
