Who called from 7156980521

I HAD A FEW MINUTES TO EFF WITH THIS CALLER - KNEW FROM THE CID THAT IT WAS A TELEMARKETER.
UNFORTUNATELY, IT WAS A RECORDED MESSAGE ABOUT GOVERNMENT GRANTS.
I HUNG UP AS SOON AS I HEARD THE RECORDING.
MAYBE NEXT TIME....
CID SAID "WISCONSIN"

Got a call today again, no message and call back is disconnected number.Calls the same time of day about 2Pm PST

This is a scam. If there were government grants available, the trade organization I belong to would send information about them in their newsletter.

It is a Robo call regarding grants.
Call is illegal because they have spoofed the caller ID and you cannot call them back.

OK....I must be on a list. Getting calls from this number constantly and the CID shows "Wisconsin". How do we stop them.
