Who called from 8603183501

I do not answer calls from callers I do not recognize, so I let this go to the answering machine.
They did not leave a message so I am blocking this number.
I am on the do not call list but that only works for legitimate businesses, so this is most likely a SCAM.

Something about lowering my energy bill

I didn't recognize the # so I didn't answer

illegally call a number on the do not call list
