Which area is this phone callinhg from?

Calls and hangs up

This is some kind of moving company out of Fenton, MO.

Unigroup (mayflower + United) moving company. Company HQ is in Fenton MO. google 'mayflower 636-305-5000' and it will give results. I didn't answer.

Received a call from 800-305-5000 on 4/18/2010.  This person left a voice mail, asking for "Leslie".  I'm not a Leslie.  Want's Leslie to settle outstanding balance of $4,018.63.  Asked me to call 800-325-3963 ?

I goggled this phone number and found it was registered to Bruce Anthony, 1611 Duke St., Alexandria, VA.

Something sounds fishy, so I'm not going to call back.  I've got caller ID so If I don't know who is calling I don't answer or if I get an 800#  or a no-name, no answer.

I'm asuming this is some sort of scam.  Not sure where to report this ?
