You can't ever log in easy/today impossible, phoned/the charges have no idea where they came from/recording, so I phone the # on back of card, usually works, but not today. Whoever answered so hard to understand/driving a car believe, so I asked her where are you, such an echo. She was in China, extreme accent, so that did not work out at all. I keep them only so my American airmails keep current.
Have no Citibank here, so have to pay online. Years ago had no problem, but now would not recommend.
