This is one of United Healthcare's many phone numbers. If you have United Healthcare, then it's not a scam call. I have UHC, so they were calling me regarding a prescription issue I've been dealing with for the last 3 weeks. If you don't have United Healthcare and you're receiving calls from them, then I suppose it would be a scam in your case.
Just a healthcare worker checking in on you to make sure all is ok. They do this periodically to all their customers. This is normal. Not a telemarketer. Just updating their records on your health.
Any time you Google a phone number and get this site you know it's a scam call. Real listings don't show up at Who Calls, they show as an individual , business or some rip off service that charges for listing information. These scam calls usually use a Magic Jack to spoof their number. I'm thinking of getting one and call the scammers back and spoof the White House number .
