Who called from 7752382067

No idea who this is from.......any thoughts?

Not sure, but they don't come across as being too bright.  Call and leave voicemail messages saying hello......hello?

I just got the same call.. and same thing it was a man leaving a message on the voicemail just saying hello but nothing else..

I let it go to the answering machine, and no message was left.
I'm in Massachusetts, FWIW.

Charity call for supporting American Veterans.  This is the second call in less than 24 hrs.  First one was last night (Sat) at 10:48PM second one was today at 3:10PM. I just let the ans machine pick it up both times.
