Call me everyday but doesn't say anything, then when I call back. It's a recording.

Received scam call

I received many calls and they told me I earned 7,000.00 $ as a fidelity grant from the American government, I told them to go away and delete my numeber from their list but EVERY single day I receive a call form that number. I think is a big scam! I say is a prank call as in the list there is not SCAM CALL

Call is from Plandome Manor, NY, claiming to be US Government offering Grants and other money. SCAM. I called today, 5/1/17 at 17:15 and the message is very unclear when it starts but then clearly states their systems are temporarily offline and to call again later. I receieved calls from this number on the following dates/times with no messages:
1. 4/21/17 at 17:31
2. 4/21/17 at 18:36

These guys are so unreal. When you listen and ask questions they get uptight and try to refer you to another no. with an fake id no. They should be flogged.
