Rec’d junk call from 414-930-2109. NEVER ANSWER ANY UNKNOWN #'s. Too much spoofing of numbers to appear next door to you, or innocuously from some distance away, but presumably appearing to be legit. No message left. IF it were important, they'd clearly state their intentions, who-how-and-where to get a hold of them, and be all too happy to show their BBB-ratings.
That essentially eliminates ALL telemarketers, hucksters, and salesmen! REMEMBER - SALESMEN ARE MERELY GLORIFIED CON ARTISTS!!! - Period!
