Citibank Bank Account Or Service Complaint

Citibank Bank account or service department,

Checking account Making/receiving payments, sending money California

I can no longer pay my bills or check any of my accounts online with Citibank. On Tuesday, - -, 2016, I went to the Citibank website to pay bills. I received a message " Time to Update Your Browser. '' My browsers are updated to the highest version my computer hardware allows. I have no way to get to my Citibank accounts. After much digging, I learned that Citibank updated their software the previous weekend. They did not provide a backup plan for account access by customers with older computers. There was no notice before or after this change. Citibank denied knowledge or involvement.
