Who called from 8642213707

i got this call at 6am...when i called back it said vm full..8642213707

I got this also but kept at it a while and found that if you hit the star key while the message plays you get 3 chances at there password to get in there mailbox .. maybe if someone can get in they can change it and there message letting people know its a scam or maybe even close out the phone account

i have tried 3707 , 707 , and 1234

also if you hit the number 5 during the message you can leave them your number to call you back if you wished so you may have a second chance to yell at them

received a call from 864-221-3707 around 1. called back and got a voice mail box that was full

Got a call from this number, when I called back it stated that the voicemail was full and was not excepting any messages.

unknown number, didn't answer - recorded voice voicemail was "<clipped> to lower your interest rates.  Press 3 to be removed from our list. "  I have NEVER asked to be called for any of this, isn't this supposed to be illegal?
