who is this?

Call came in on 12/28 @ 4:29 p.m.  I didn't recognize the number so didn't answer.  They didn't leave a message.

Been receiving calls from this number for the past 10 days, sometimes several times per day.  They don't leave a message.

I started getting calls from this number on 4 days ago and now it is 1x per day usually in evenings and even after midnight.  I googled the # b/c I didn't recognize it and don't know anyone from Portland, OR.  Very annoying- the same as you all say- there is never a message

She stated she was doing a survey for the yellow pages

Called at 9:00pm. Wanted me to take a survey about the Yellow Book. Told them it was too late to be calling people and that paper phone directories were an outdated concept.

Hey this is another one of those pesty callers that call constantly and never leave a name or message. I finally answered and got a person and asked they stop calling me. Hopefully it worked. (smoehow I dought it)

googled MARC RSCH and it comes up as a research company, they have been calling  for 6 days, sometimes more than once a day.  They don't leave a message.  They have a website www.marcresearch.com
