Called half a dozen times in 3 days. I don't pick up. No message.

Calls me 3-4 times a day,sometimes at night.I never pick-up.

They call several times a day...very annoying.

Calls multiple times/day every day. Doesn't leave voicemail. Accidentally answered today. They tried to offer some kind of cellular security system. I said no thanks, they kept talking. I hung up. Number is now blocked.

6/27 CID 'Research Center' - several rings, disconnect, no msg - typical scam/robo call pattern - from above post seems like a scam call - recommend block, if possible

Called a few minutes ago; CID says 'Reseach Center' , yeah, right. Scammers and thieves more likely. Blocked! Die, scammers, die!

RESEARCH CENTER = Scam center - Block if U can or ignore if U can't.

multiple calls today - no message left

Called 3 days in a row. Calls says it is from Damascus, MD. Didn't answer and no msg is left. Blocked number.

Called Back , voice mail says if you don't want to participate in their survey e mail them and put the phone number that you don't want them to call in the body of the email sounds like they are research and development and I am the King of England ........Ignore
