Complaint Review: Legacy Visa Card First National Bank

I recently received a phone call on my cellphone from a person whom said, " I am calling about you Legacy Visa Card account and I see you are overdue on your payment, and I would like to get this caught up for you." I said, what card? He said, Your Legacy Visa Card with First National Bank. I said, I do not have a Legacy Visa Card, he said well I see you are not going to cooperate so I will mark this account closed. I said, Sir what is this, what is the account balance on that card? He said, well mam I see you unwilling to honor this so I will mark this account closed. I said sir I have never had such a card. and he hung up on me. I am wondering if anyone else has ever had this happen? And really...it was very unreal. I have never heard of them ever. What is there I can do about this if anything?
