This number just called me and left a recorded (automated) voicemail. The recording said they are calling about an important Wellness Program Coaching program relating to my employer and United Healthcare. They left a number to call them back at 1-800-707-2021 to set up an appointment with a Personal Wellness Coach.
This is telemarketing, phishing, and scamming. If you have a Samsung smartphone you can add numbers to a "reject list" which means your phone will never ring with from this number again. Get one.
