Received a call from this number yesterday. I said hello but nothing else. The man on the other line said hello twice and then he said "Can you hear me". I hung up at this time. Heard from several media sources that this is a major scam who uses your "yes" response to charge you a fee for responding.
SCAM ALERT! Caller ID: Charlestown, RI Person Identified themselves as Victor Brown from United Health Solutions. Gave return call number as 855-851-8080 (bogus). Gave mailing address as 930 N Market St, Wilmington DE 19801 (bogus). Seems to be foreign (heavily accented individuals) preparing to scam Medicare Providers out of some $$$. Selling various braces at no cost to individual and delivered to your door. Being disabled I was able to waste at least 13 minutes of their time for something to do this morning. :)
Called twice now. First time, heard some people in the background, and then they hung up. Second time, a man with a heavy accent said, "hello?" I said "hello" back, and he hung up. Sometimes I'm just in the mood to screw with these folks, so it's too bad he hung up.
