Citibank Debt Collection Complaint

Citibank Debt collection department,

Credit card Cont'd attempts collect debt not owed Debt is not mine California

A representative called me from - - stating that I owed a debt from Citi Bank and that they were going to sue me if I did not pay them $16000.00. I did not know about this debt, so the representative said he would transfer me to the fraud department. After sitting on hold for over 10 minutes, I call back the number that called me ( from the caller ID ), talk to the rep again and he then transferred me again. The man that answered said the debt was from 2005 ( over 10 years old ) and said " You must have been transferred here because you do not want to pay ''. I said if this debt is from 2005, it is over 10 years old and is a time barred debt ( Cal. Civ. Proc. Code 312 et seq. ) so he can not report it, nor can he sue me for it. He said he was from a legal firm and would see me in court and hung up.
