Who called from 4082906944

Multiple calls, this time calling themselves "National Renewable Energy Center". Won't honor Do Not Call requests, has been reported to FCC.  It seems nothing will stop these people short of litigation.

multiple calls from this number and they put spades and plus signs to try to make it look different each time, so annoying, blocked it.

Called and tried to pretend they were from the State of CA offering energy rebates. Very shady.

Every evening a call comes from this number and no body answers the phone. This is very annoying

Called yesterday from -6942 and asked for the homeowner. Told them this is my cellphone & I don't own a home. They said they would note it so I wouldn't receive calls again. Today they called from -6944 and I didn't answer. Blocked both numbers.
