message was caller who said we owned money to the irs.

Just called here.  Same scam, new number.

The message said he was James Kasten and ignoring this call would lead to a federal indictment in a grand jury.  He had a a British accent.
This is a scam.

caller id "6362870396". Left no message

also received an automated call from James indicating this was their second attempt to contact me regarding an IRS matter and that if I ignore calling them it would lead to a federal incitement. IRS doesn't call people.Don't be scared into returning the phone call. They'll just feed you more lies and scare you into giving them personal information.
