This is a phishing tactic. UHC and Medicare scam. They need to prosecute whoever Street Beats is for misrepresentation. Someone is trying to steal identities. Don't answer it.
It's an automated system call asking personal questions. Don't give them any answers and just hang up. Then if you do have United Health Care Insurance, call them from the number on the back of your card. I hung up after they wanted to verify the name. Too bad there's no live person they would've been given an ear full.
