I've been an AMEX customer for a long time and I'm starting to get frustrated with them for stupid stuff. One example, for some unknown reason they cannot seem to correctly reflect a card balance on their online system! Over the last couple of months, I have noticed that even after I receive an email confirming that my payment has been received it does NOT show up when I log into my account for up to 48 hours after the payment was received. I just don't understand what is going on! They can show a pending transaction minutes after I swipe a card but they can't show that they have gotten $13k of my money on this payment for 48 hours.
