A credit card cautionary tale:
I booked a London hotel last week for an upcoming trip. I used a popular but shall-remain-nameless U.S. credit card to cover the pay-in-advance rate.
When the hotel put the charge through -- 3 days after I made the booking -- the card company emailed an alert to me, asking "Is Everything OK?" with the international charge for $XXXX.
I clicked the "Everything Is OK!" option and immediately got a "Thanks! Don't Worry!" response from the card company.
I thought that response indicated the hotel's charge had been accepted. I was wrong.
I phoned the card company a few minutes later and learned the charge had been rejected before the first alert email had been sent to me. Nothing in their initial message indicated the charge had been rejected. And, to be fair, nothing in the subsequent "Thanks! Don't Worry!" response said the charge had been accepted.
After explaining, and complaining, to the card company, I phoned the hotel and waited until they put the charge through again and assured me it had cleared. (And followed up with confirmation of that via email, which was nice.)
If I had not phoned the credit card company and, instead, had assumed their happy message meant something it did not, I risked losing the reservation or even arriving at my London hotel late at night to find my booking long gone.
