Who called from 2402107101

I got this call today on my business cell phone. Thinking it was a customer I called it back. I got an automated message saying I was removed from the preferred calling list.

If you want to remove yourself just return the call!

Just got a call from 240-210-7101. No voicemail.

Called them back. Got a message that I have been removed from the calling list. Very suspicious.

recieved a call on 2/21/08

got a call @1702 on 2/20.  Since so many others have also gotten a call from this number, I guess it must be spam.

I got called yesterday from that number at 10:15 AM feb.21 and today at 11:oo AM feb.22, 2008. Who ever doing these unwanted call need to stop.
