Hello! How may I help you?
I'm trying to make a purchase and my credit card keeps getting rejected.
Oh no. I am sorry to hear that.

Will you enter the credit card again to see if it'll work please?
Ok I have done so That didn't work
Still rejecting?
Yep, still invalid
Okay. Another option is to log out and back in.

Oh no!  Will you please check the expiration  date to make sure the card is still current?
Oh my gosh, I'm sorry! My fault, it does appear to be expired!
Oh no!  I'm so sorry. Hopefully you can renew it soon and shop!
I will have to look into requesting a new card. So sorry, thanks for your help.
Is there anything else I can do for you?
