"Unknown" at 234-512-3451 called at 6:29 am, 8:44 am, and 9:55 am this (Saturday) morning. I didn't answer any so I don't know anything more. From what I read this is not unusual.
This number has called at10:41 am and 6:44 pm March 26th, then at 1:48am 9:02am March 27th. You would think the phone company would band them after all the complaints. No one on the other end, when you call it back you get a message saying: "I sorry but your call can not be completed as dialed".
