Received 4 calls from this number, 3 of which were on the same day. I finally answered the 3rd call and it was a guy doing a health and wellness survey from OU Medical. Stated he wasn't selling anything. I hung up and blocked the number once he identified himself.
I had several missed calls from this number and finally answered it. It was a health survey for Oklahoma. They didn't want any identifying information, not even my name, so I think it was legitimate. It would be a pretty useless scam, she just asked about various illnesses, my insurance situation, frequency of doctor's visits, smoking/drinking, etc.
I get calls from this number but they leave no messages. I have no clue who they are and don't intend on answering from an unknown caller. If the call is from OU Medical Center, I have no idea why they would be calling me because I live in Southern California.
