A typical Medicare scam (“benefits advisors” aka “Medicare rewards card” scam) where they’re phishing for people’s Medicare numbers and social security numbers. They are calling from numerous spoofed numbers and leave annoying voicemails to call them back. You have to press “1” when you call this number back.
I called (203) 884-1960 at 2:50 PM CST and had a scambitch answer.
