Who called from 6463571823

Left message that said they are the I.R.S. and that they were fileing a law suit against me for unpaid taxes.

This is a scam...do not trust!!

Reported number to federal trade commission and blocked.

Received 2 calls 45 min apart. Message states "about this case file please contact our department." Sketchy.

got two messages close together and called them back. They even answered "internal Revenue Service"
