I just answered the phone...a women was speaking on the other side, talking about a health insurance survey. I answered the survey except the personal information part. The whole survey lasts for about 15-20 mins. When I tried to verify who is conducting this survey, she said it was the MASSHEALTH or something and then gave me a number 18008412900. Anyway, since she didn't ask for personal information, I have no bad feeling about this call.
