AcmeBrands, how may I help you?
Hello, I need some help with my credit card, it keeps being rejected
Let me help you with that.

Can you try to enter your information again?
Just tried that, it still doesn't work.
Ok

Can you log out and then log back in, and try entering your information again?
Okay, still doesn't work.
I am sorry to hear that

Could you check the expiration date on the credit card that you are using?
Oh shoot, the card I am using expired last month. My fault, I feel so silly.
It's okay, happens to everybody. Can I help you with anything else?
Nope, that's all. Thanks
Have a good day.
