Didn't answer the call. Read the comments here. Called the number back and got a recording that let me have our # removed (took 30 seconds or more to get to that). "Police Int'l" looking for participants for a dry eyes study.
2:00 p.m. Just got this call and have caller i.d. - the name read: "RESRCH STDY" .... they let that &^%$ phone ring at least 30 times. I would not pick it up as they'll only call back. The incessant ringing drove me to distraction. I also have an unlisted number. Grrrrrrrrrrrrrrrrrrrrr.
Recorded message: Doing research and trying new meds for gout. Will pay $$ if you qualify. Press 1 to speak to someone (I didn't) Press 2 to be permanently removed from list. (I did). However, this same number called about 2 weeks ago for a research study for chronic low back pain. I pressed 2 then too, but still received a call today.
