I believe I may have discovered a way to stop this moron. I'm going to wait another couple of weekdays before I'm sure. Will advise. Meanwhile, at the end of each of the last two days I filed complaints on the donotcallregistry.gov for every one of the calls: total 17 complaints. Two different numbers have been calling. I think calls are coming from the same caller. It's unlikely the FCC would have acted so quickly.
