They call almost every day. Never there when you answer.
They call using several different Caller ID's, all generally numerically close to this one. No matter which one you call back, they all report as not being in service.
God help you if you get on their "list". It appears to be impossible to even talk to them (computer or live body), so of course, it is impossible to request removal. We are on DNC (State and NW). Does no good.
Have reported to FCC many times and now have a trace on the line.
Keeping a call log.
