Received call saying sumthin bout a nurse pls return call to Discuss coodinations of benefits

I called the number back, and turns out a very nice woman identified herself as a registered nurse and said the call I had gotten was from a group affiliated with United Healthcare calling to see how I was doing...that they make routine calls after someone has been hospitalized or who appears to have a condition like diabetes, which I do not, and that it's a service all the insurance companies offer, "since on the weekends or h olidays you may not be feeling so hot, so you can call us and tell us your symptoms and we can let you know if it seems serious and you should to go the hospital, or how to manage it.
It's a wellness program and it's already covered."
I explained I had doctors and just didn't like getting calls from strangers about health matters or any matters sharing personal info over the phone and she said I could opt out. But I would need to give her my UH number. "If you don't want one of the free services, we can take you off.
I politely explained I'd call the 800 number to UHC and let them know since at least I'd know who I was speaking with."
A plausible story, as far as she went, but didn't want to waste any more valuable time. So I thanked her and wished her a nice day, Now you all know the rest of my story.

THEY CALL 1-2 Times a week. They would say this is your final notice to lower you credit card debt. My wife waited to tell them we are on the no call list and they switched to putting you on hold as soon as you answer. So I hang up.

The caller ID shows as OPTUM.  I answered but there was no response.

It looks like they are using this number again and claiming to be United Health Care.Most of the dates on the posted messages are from 2013 and 2014. I answered and a very soft spoken female asked for me only after one of those long pauses. She wanted me to speak to an RN.I said I wan't interested but go ahead and let the RN talk. When she asked me to verify my date of birth and address I said if you're calling me you should know it. Then she tried to give me a call back Number.It has scam all over it. I hung up and blacklisted them. thank you all for posting I get so many of these kind of calls and I appreciate being able to look them up here.
