On Monday, December 15 at 2:44 PM, I received a call from this number. There was some background noise which made it difficult to understand the male-voiced caller. He did not identify himself but asked "Did you send me an e-mail?" and I responded "No, I didn't" and he promptly said, "I'm sorry, I must have the wrong number." I tried to ask his name at this point, but he had already hung up. I do not know anyone living or working in the Washington DC area, so I have no idea if this was actually a harmless wrong number or a suspicious crank or spam type of call. If anyone can provide information re: the ID of this caller(or perhaps company) I would be grateful to receive this info.---Thanks!
