Citibank Bank Account Or Service Complaint

Citibank Bank account or service department,

Other bank product/service Making/receiving payments, sending money California

I have a credit card with Citi bank and sometimes like to go and pay the credit card bill with cash in person at a local branch in -, CA. I have been informed by the branch that since I do not have a checking/savings account with Citi bank I have to provide my drivers license, social security number and my job description. I was shocked that they told me they can not take a cash payment without all my personal information. I told them they have all that information when the credit card application was filled out in 1996 ( when I first applied for the card ). They said this was a federal law requiring all this information. I bank with other banks and have not had a problem with cash transactions.
