Who called from 2021100014

I have received 19 calls fro this number. Never anyone on he line. If you call it ack it says number no good.

don't call these back.  then they register that the number called is live.   just ignore them.

Dead air when I answered.

calls indicating you have a grant fro education from fed for $7000..RIGHT!!!!!!!!!!!!!!!

I got a call from 202-110-0014.  The caller was not American but said he was calling from the US Treasury.  He claimed I had "won" grant money.  I knew the call was bogus and pressed him for more information about who he was and then he hung up on me.
