What To Do If You Cannot Login.
Site:
Citibank set up another website www.myciti.com
You can verify this by calling their online tech support at 1-877-660-1132 or
1-800-347-4934
That is the only way I have been able to use their online services since the problem started.
If you cannot login by either the regular website or the alternative website, definitely call them.
They are under the impression that if you do not call, then everything is working for you.
Hope This Helps Someone.
