I have tried many times on line to change my credit card number and unfortunately I have not succeeded. If you can tell me that my old credit card doesn't work, then you should provide a way to change it. You have not. I'd like to change my card number and pay my bill but I don't know how and the site is not helping me to do it. Please tell me what to do. User's recommendation: do not to change your credit card. Yves Rocher can't handle new ones!
