Better "Error" Messages
We tried to pay an invoice with my wife's card and got "an error has occurred -- try again later", or something like that. We triple-checked our credit card info, tried again, and got the same not-helpful message. Then we tried my card and got the same not-helpful message.
That night I picked up my cell phone to check e-mail and found three text messages from Citibank asking me to verify "an unusually large charge". I signed on to their site, and sure enough there were three rejected charges. Once I verified the charge and tried again this morning, it went through.
What kind of garbage message is "an error occurred"? Give your customers a clue, and avoid extra work for them, for you, and for the credit-card issuer. How about: "Your payment was rejected ["declined" is a silly misdescription] -- check with your credit-card issuer"?
Grump!
