Hi! How can I help you today?
I'm trying to make a purchase, but my credit card keeps saying invalid.
Oh no!

Can you please try to re enter the information?
I did but that didn't help
Try logging out then in of your account.
Ok. That worked. It's accepting it now.
Great! Is there anything else I can do for you today?
No, thank you
Fantastic, have a good day!
