Finally answered this call after repeated attempts.  The person said I was late on my payments and wanted to know when I would make them.  The call was supposedly on behalf of Citicard.  I asked what my account number was late and he did not answer but started phising for personal information.

I called Citicard and asked them my account number.  Since I called Citicard directly, they provided me my account number after they asked me some personal questions and I answered them.  I reported the 877 number that was made and Citicard told me it was not on their list.

Beware of suspicious calls.
