I get both of the 1990 and 1991 numbers. I wouldn't count on what that service person said. I've heard that one too and still after two months, it's happening everyday.

has called 5 times since Aug 24, no message

Calls on a daily basis, sometimes 2 to 3 times a day...getting really annoying, no messages left, so i just pick up and hang up now...what ever happen to the DNC?

Have received about 30 calls from this number in the past week or so. Also get calls from the number ending in 1991. No one there, just a beep.  We get calls as late as 11pm - EXTREMELY ANNOYING!!!

I received about 60 of these calls over the past 2 weeks and FINALLY when I picked up tonight, someone was on the other line!  It's a government agency conducting studies of Radon within the home (?) and they asked if I would like to participate.  I asked them if they had been calling my number non-stop and they admitted that they had called a lot.  I asked to be taken off of their list and they told me "It's a government study so that's impossible to do."  I said do it.  They asked if I would still like to know what the study was about and I said no and hung up.  Hopefully the END!!!!!

Getting calls everyday for several days now, and late at nihgt....same thing, nobody there, VERY annoying!!
