Federal loyalty grant hoax call from US Treasury

Scam continues... got a call today from a 'blocked' caller indicating that we had received a $7500 grant for being "excellent citizens" - one of 1500 such people selected. They claimed no taxes or fees were owed on this sum. They were based in Washington DC, gave me a reference number and asked me to call them on a 202-number since I said I was driving. Beware!!

Scams are already listed on the IRS and treasury websites.
