call came at 2am sunday morning.  Thought it was a call from a hospital, like someone was hurt, so I answered ( I normally screen).  It was NorthStar credit monitoring, telling me that my "card" had been shut down due to fraud, and they would need the acct # to reopen it. didn't say what card ( i have like 11, all with zero balances).  Hung up right away.  checked all my cards and they are fine.  total scam.
