Hmmm, caller ID claims to be United Healthcare but when called you get a recording asking if you would like to do a survey after the call. If you say yes or no it disconnects your call every time.
Got a call from this Number. 4-5 mins. Earlier before I called back ( they left no message and didn't recognize the number). I called back. Auto message said it was United Health Care but presently they are closed and to call back later. This seems pretty strange since they had called me about 4-5 minutes earlier.
