Who called from 8607267916

Calls all the time never leaves a message....

called many times. left no msg

They've been calling but not leaving any messages.  I picked up for first time and they asked to speak to person in charge of electric bill. When I asked who they were they would not say and reitterated that they want to speak to person in charge of electric bill. I hung up on them.

Continuously calls, leaves no message.  When phone is picked up demands to know who is in charge of phone bill.  Very irate and intimidating person.

I keep getting phone calls and they do not leave any messages.  I am on the do not call list.
