unknown caller left no voice mail also got a call a day before from631-652-1575 no voice mail called both numbers back and got recording that the number is not correct.
I got a call from this number, I think this is the first time. I don't have long distance so I could not call it back. When I picked up, there was dead silence on the line, then a click, then I hung up. It's been an hour, and they did not call back. I read other reports about this number being related to Exel, which is my electric company, so I will call them.
