It's very difficult to block the calls from this company as they call from a different spoofed number each time. I've recorded eight different phone numbers for the exact same recorded message:
"Hello! The state has determined that you qualify for a new energy release program where you may be eligible to receive up the a $21,000 tax credit. Press 5 for additional information. Press 3 to no longer receive these calls."
Needless to say, pressing any number will not stop the calls.
