Called me three times today. Didn't answer first time. No message. Answered "hello?" second time. Heard background noise but no one responded then they hung up. Third time, I answered and they asked for "Jennifer" (my name is Jhen so I told them they had the wrong number, they apologized and hung up). When I tried to call back (to find out who they were), the phone is just dead air, doesn't even ring! I also tried calling this number from my landline with this same result. Who is this and how do they have my number?!

I have received several calls from this number.  No one ever leaves a message.  I tried calling the number, but it rang multiple times and then I received a dial tone; no one ever answered.  I am going to file a complaint.  I tried texting the number and asking them to quit calling, but it is a land line.

Called a few minutes ago and asked for me by name.  Wanted me to be part of
a survey.  Told him, not interested, he hung up.

Called, but left no message [caller ID says "Dover, MA"].  Some weird background noises [probably a call center or boiler room operation?].

This is a very persistent "Research Center;" don't know what exactly what they are "researching," but we blocked the number.
