don't call them back, its a scam. left 1-888-986-8328 as a call back number. I googled that number and didn't find anything, called united directly and they had no idea what I was talking about.

Received a voicemail staying they are from United health care coordination of benefits department.  Sounded suspicious so I called the number on the back of my ID  card and they said it was a fake call and they would never ask me for info via phone . Do not give them info!

Caller ID says 781 355 7530 Dedham, MA. "Dee Dee" slight accent left a voicemail saying "United Healthcare" and left this number to call back 800 258 6979. I got the same voicemail yesterday from a totally different number 925 983 4358 Bishop Ranch, CA asking that I call back the same 1800 #. I called United Healthcare to inquire about this and they have no affiliation with these scam calls. Do not answer or give any information and report!

Scam !! Said they were from United. Chinese guy with poor English trying to obtain private information

Got a several calls from this number.  When I spoke to him, he said he was from United Healthcare and needed to verify my identity with my zip code.   I told him that *he* needs to verify he is from UHC first because I didn't trust him, and to send me an email.   He insisted I call back on an 800 number.   Pfft.   I told him to just include the number in the email.   Needless to say, no email has come through.
