I have received several calls from 301-306 and several last 4 numbers. I think this must be the same (group?) scammer(s). Obviously, whoever this is "spoofs" caller ID. The last call was some heavily accented male who identified himself as "Ralph", and was pimping "duct cleaning". Last week it was "Medicare Supplement(s)". Before that, it was some over-stimulated female hustling "reverse mortgages". I would like to find out who this REALLY is, so I could alert the authorities. I think if I did that, it would save the rest of us from a lot of bu**sh*t aggravation. Meanwhile, keep up the good work of reporting these scammers, not participating in these criminal enterprises, and do not answer any calls that come from numbers and/or persons you don't recognize.
Say, aren't you the guy who keeps claiming you are a retired "problem solver for Federal Law Enforcement"? If that's true you should have not problem tracking them down.
