What more details do you want to know? Your extra-cards that I and my wife and I had on our keychain ring and were using them for years, are not readable anymore by your reading equipment at cashier's. We were told to contact your offices to ask for a replacement. I called and provided information for one card and when I tried to give a second card info, I was told that you can provide only one at a time. The phone operators are not friendly at all, we didn't get even the first card and no info was given when we can ask for the second one.
