I received 7 calls from this number today, 7/28/2009. I let the answering machine pick-up but they never leave a message. When I called the number back the operator said the number couldn't be completed as dialed.
I got several calls from this number also 202-909-5412 and also 301-955-6274 and I picked up the phone and was told the aggravation would get worse and hung up. WEIRD
