Who called from 2021000000

none stop calling ,starting at 8 in the morning to 8 at night

This 202-100-0000 keeps calling I just don't answer.. And they never leave a message! Says this call is originating out of the district of columbia

Nothing. Didn't answer. Just annoying.

when I answer  and say Hello there is no answer from the caller.

recived a call from this number. they do not speak english very well but said i would get a grant that i would not have to pay back. i told her that i knew this was a scam and hung up on her. i think this has to do with filling out to get free samples in mail. they ask all these guestions but call you anyway.
