Who called from 2020000000

My grant was for $9000. Said it was for being a good american.

Same here so is it a scam

Just answered and was told they were with the Federal Government in Washington and wanted to give me $9,000 in grant money.  Spoke a broken foreign language.   I asked to be put on the do not call list and they promptly hung up on me.

I got the same grant call twice. And said not interested and now this number calls like every day

How do I block the number. I get these calls on my land line.
